AB  - Naraščajoče povpraševanje po varnih industrijskih procesih je pripeljalo do razvoja in uporabe okolju prijaznih trdnih katalizatorjev, namenjenih za uporabo pri kislinsko kataliziranih reakcijah z dodano vrednostjo. Kislinska kataliza je eden najpogostejših procesov v kemični industriji. Industrijsko pomembne organske trasformacije vključujejo esterifikacije in transesterifikacije, eterifikacije, dehidracije, oksidacije, acetilacije, sililacije, sintezo biodizla [1,2]. Trdni kislinski katalizatorji, znani kot "zeleni katalizatorji", se uporabljajo kot nadomestek za homogene kislinske katalizatorje. Vsebujejo več okolju prijaznih komponent, hkrati pa zagotavljajo večjo aktivnost in selektivnost v primerjavi z obstoječimi homogenimi katalizatorji [3]. Primer heterogenega katalizatorja je mezoporozna silika - modificiran SBA-15, ki se uporablja za številne
organske reakcije. V tej študiji smo se osredotočili na sintezo trdnega kislinskega katalizatorja na osnovi mezoporoznega silike SBA-15 z inkorporiranim kovinskim Al. Z ujetjem kovine v silikatno matrico se katalizatorju izboljšata aktivnost in selektivnost, postane bolj temperaturno obstojen in pridobi večje možnosti za ponovno uporabo. Sintetiziran katalizator smo karakterizirali z adsorpcijo-desorpcijo dušika (BET), živosrebrno porozimetrijo, Fourierjevo transformacijsko infrardečo spektroskopijo (FTIR), vrstično elektronsko mikroskopijo (SEM), dinamičnim svetlobnim sipanjem (DLS), rentgensko difrakcijo (XRD), difuzno refleksno spektroskopijo, termogravimetrično analizo (TGA), temperaturno programirano desorpcijo (TPD) in temperaturno programirano redukcijo (TPR). Nadalje smo z uporabo tega katalizatorja izvedli vrsto reakcij esterifikacij oleinske kisline v metanolu s proizvodnjo metil estra oleinske kisline. Vse eksperimente smo izvedli v
laboratorijskem šaržnem reaktorju. Preučevali smo vpliv reakcijske temperature (55, 60, in 64,5) °C in mase katalizatorja m (0,2, 0,4 in 0,6) g na presnovo reakcije. Učinkovitost reakcije smo spremljali z določanjem koncentracije oleinske kisline in metil oleata z uporabo GC-FID. Preverili smo ohranjanje aktivnosti katalizatorja po večkratni zaporedni uporabi. Študijo smo nadgradili z določitvijo kinetičnih parametrov izvedene reakcije.

AB  - The consequence of drastic reduction in fossil fuel reserves has forced the
scientific community to find and develop new ways to exploit renewable resources and
optimize the process of polymer materials production. The aim is to obtain applicable
polymer whose complete life cycle is set in ecological framework. Poly(lactide) (PLA)
meets these requirements as biodegradable polyester whose monomer is derived from the
plant feedstock containing carbohydrates. PLA could be prepared using the different
synthesis routes, but from the point of energy saving, as well as environmental protection,
the microwave synthesis of PLA is the best solution. In this work, poly(L-lactide) were
synthesized in microwave reactor. Reaction time was varied, while the other parameters of
the synthesis were constant. The structures of obtained polymers were confirmed by Fourier
– transform infrared spectroscopy (FT-IR). For determination of molar masses of poly(Llactide) samples, the gel permeation chromatography (GPC) was applied. Thermal
properties were investigated by differential scanning calorimetry (DSC).

AB  - Starting from the main relation for closed thermodynamic systems for maximum work of reverse processes, a general model for determining the minimum volume of the tank containing compressed ideal gases, nitrogen and oxygen, as the main constituent components of the air has been developed. In addition to thermal and mechanical, in the observed complex system there is a concentration imbalance. In this way, the analyzed isolated system fulfills the conditions for obtaining work. In determining the model, it is assumed that the initial parameters of the gas in the tank, the state of the environment and the necessary energy (maximum work) to be obtained from the given gas are known. Thermal and mechanical imbalance is realized through an isentropic and isothermal state change, while the problem of concentration imbalance, considering the observed gases, is solved on the basis of the relation for the volume fraction of the component in the gas mixture, i.e. the partial pressure of the observed gas in the environment. In addition to the analytical, in order to control the obtained results, a graphical solution of the observed problem was given using the p-v i.e. T-s diagram. At the end of the work, the application of the model is illustrated on a practical example from practice, where the minimum volumes of the tank for nitrogen and oxygen as characteristic gases, were defined. In order to compare the results, the volume of the tank in which the air is located is determined under the same initial conditions, i.e. the same parameters of the environment. The obtained results can be used in practice for dimensioning or estimating the actual volume of the reservoirs for technical gases, since the actual processes are generally irreversible from the thermodynamic aspect.
AB  - Polazeći od glavne relacije za zatvorene termodinamičke sisteme za maksimalan rad povratnih procesa, u radu je izveden opšti model za određivanje minimalne zapremine rezervoara u kome se nalaze komprimovani idealni gasovi azot i kiseonik koji su glavne sastavne komponente vazduha. Pored termičke i mehaničke neravnoteže, u posmatranom kompleksnom sistemu postoji i koncentraciona neravnoteža. Na taj način u analiziranom izolovanom sistemu su ispunjeni uslovi za dobijanje rada. Pri određivanju modela, pošlo se od pretpostavke da su poznati početni parametri gasa u rezervoaru, stanje okoline kao i neophodna energija (maksimalni rad) koji treba dobiti od datog gasa. Termička i mehanička neravnoteža ostvarena je preko izentropske i izotermske promene stanja dok je problem koncentracione neravnoteže, s obzirom na posmatrane gasove, rešen na bazi relacije za zapreminski udeo komponente u mešavini gasova odnosno parcijalni pritisak posmatranog gasa u okolini. Pored analitičkog rešenja, radi kontrole dobijenih rezultata dato je i grafičko rešenje posmatranog problema korišćenjem p-v odnosno T-s
dijagrama. Na kraju rada primena modela ilustrovana je na jednom primeru iz prakse gde su određene minimalne zapremine rezervoara za azot i kiseonik, kao posmatrane karakteristične gasove. Radi poređenja rezultata određena je i zapremina rezervoara u kome se nalazi vazduh pod istim početnim uslovima odnosno istim parametrima okoline. Dobijeni rezultati u praksi mogu poslužiti za dimenzionisanje odnosno procenu stvarne zapremine rezervoara za tehničke gasove s obzirom da su stvarni procesi sa termodinamičkog aspekta uglavnom nepovratni.

AB  - The analysis and sizing of the distillation column for the separation of n-heptane-n-octane mixture were conducted using a traditional method for modeling and describing distillation systems, combined with modern software systems. Basic parameters were obtained by using rigorous separation and calculation procedures for the separation of the mixture used. These parameters describe distillation process, as well as basic dimensions and physical and hydro-dynamic parameters of the distillation column. Analytical and numerical methods were used for the analysis, modeling, sizing and operation control of the system. The previously used calculation methods were verified by developing the program for the case of the binary mixture. The values, obtained in this program were used for further description of the system, as well as sizing and determining basic physical and hydro-dynamic properties such as column diameter, and pressure drop. The key parameters describing this system are optimal reflux, minimum reflux, number of theoretical stages and minimum number of theoretical stages. Changes of the number of stages, reflux and column diameter were monitored as a function of mixture composition, as well as flow of the mixture at entrance of the column. Key words: distillation of binary mixture, rigorous calculation procedures, design methods, distillation columns

Primjenom rigoroznih postupaka razdvajanja i proračuna za razdvajanje smješe, praćeni su osnovni parametri, koji opisuju tok
destilacije, kao i osnovne dimenzije destilacione kolone sa ventilskim podovima i osnovne fizičke i hidro-dinamičke parametre (dijametar kolone i pad pritiska). Za analizu, modelovanje, dimenzionisanje i kontrolu rada ovog sistema korišćene su grafičke, analitičke i numeričke metode.
Razvijanjem programa verifikovane su ranije korišćene metode proračuna, a vrijednosti dobijene proračunom su poslužile za dimenzionisanje kolone. Ključni parametri koji opisuju ovaj destilacioni sistem su radni refluksni odnos i minimalni refluksni odnos, broj teorijskih podova i minimalni broj
teorijskih podova. Promjene navedenih veličina praćene su u funkciji sastava smješe, kao i protoka smješe na ulazu u destilacionu kolonu.

The previously used calculation methods were verified by developing the program for the case of the binary mixture. The values, obtained in this program were used for further description of the system, as well as sizing and determining basic physical and hydro-dynamic properties such as column diameter, and pressure drop. The key parameters describing this system are optimal reflux, minimum reflux, number of theoretical stages and minimum number of theoretical stages. Changes of the number of stages, reflux and column diameter were monitored as a function of mixture composition, as well as flow of the mixture at entrance of the column. Key words: distillation of binary mixture, rigorous calculation procedures, design methods, distillation columns, Tradicionalne metode modelovanja i opisivanja destilacionih sistema, u kombinovanju sa savremenim softverskim paketima, poslužile su za analizu rada i dimenzionisanje destilacione kolone za razdvajanje binarne smješe nheptan-n-oktan. Primjenom rigoroznih postupaka razdvajanja i proračuna za razdvajanje smješe, praćeni su osnovni parametri, koji opisuju tok
destilacije, kao i osnovne dimenzije destilacione kolone sa ventilskim podovima i osnovne fizičke i hidro-dinamičke parametre (dijametar kolone i pad pritiska). Za analizu, modelovanje, dimenzionisanje i kontrolu rada ovog sistema korišćene su grafičke, analitičke i numeričke metode.
Razvijanjem programa verifikovane su ranije korišćene metode proračuna, a vrijednosti dobijene proračunom su poslužile za dimenzionisanje kolone. Ključni parametri koji opisuju ovaj destilacioni sistem su radni refluksni odnos i minimalni refluksni odnos, broj teorijskih podova i minimalni broj
teorijskih podova. Promjene navedenih veličina praćene su u funkciji sastava smješe, kao i protoka smješe na ulazu u destilacionu kolonu.",

AB  - Hydrogen could be the important energy sources of the next period provided that its production,
transportation, and storage are solved. In this paper review of the production of hydrogen from
lignocellulosic feedstock is given. The process is analyzed in all its phases and alternative
solutions. Two different, alternative biomass gasification process - direct and indirect, and two
different, alternative reforming model - partial oxidation and steam reforming are described. Gas
cleaning is also provided with two different, alternative concepts - cold and hot cleaning.
Conversion of the working gas and the separation of hydrogen from CO2 and other impurities are
still used as a method in the tubular membrane reactor - all in one place which significantly
reduced the cost of 1 kg of hydrogen. In all these processes is especially taken into consideration
on the integration of energy in the process, which is also significantly contributed to the better
price of hydrogen.
AB  - Vodonik bi u narednom periodu mogao postati značajan izvor energije jer su njegova proizvodnja, transport i skladištenje uglavnom riješeni. U ovom radu se daje pregled proizvodnje vodonika iz lignoceluloznih obnovljivih izvora. Proces je obrađen u svim njegovim fazama i alternativnim rješenjima. Tako su obrađene dva različita, alternativna, procesa gasifikacije biomase - direktna i indirektna i dva različita, alternativna, reforming modela - parcijalna oksidacija i reformiranje vodenom parom. Prečišćavanje gasa je, takođe, dato sa dvije različite, alternativne, koncepcije - hladno i toplo prečišćavanje gasa. Konverzija radnog gasa i razdvajanje vodonika od CO2 i drugih primjesa se danas radi u membranskom cijevnom reaktoru - sve na jednom mjestu što je znatno smanjilo cijenu koštanja 1 kg vodonika. U svim ovim procesima je posebno vođeno računa o integraciji energije u procesu što je takođe znatno doprinijelo ekonomski povoljnijoj cijeni vodonika.

AB  - The world is faced with the consequences of drastic reduction in fossil fuel reserves, because of their widespread use, not only as an energy source, but also as a feedstock for monomers obtaining. In order to solve this problem, the scientific community has focused on finding the new ways to exploit renewable resources and optimize the process of polymer materials production. The aim is to obtain applicable polymer whose complete life cycle is put in ecological framework. Poly(lactide) (PLA) meets these requirements as biodegradable polyester whose monomer is derived from plant feedstock containing carbohydrates. Different methods can be applied for PLA synthesis, but from the point of energy saving, as well as environmental protection, the microwave synthesis of PLA is the best solution. The use of microwaves enables homogenous heating of reaction mixture, lower consumption of organic solvent and drastic reduction in polymerization time, obtaining, in the same time, high molecular weight polymers.

The aim is to obtain applicable polymer whose complete life cycle is put in ecological framework. Poly(lactide) (PLA) meets these requirements as biodegradable polyester whose monomer is derived from plant feedstock containing carbohydrates. Different methods can be applied for PLA synthesis, but from the point of energy saving, as well as environmental protection, the microwave synthesis of PLA is the best solution. The use of microwaves enables homogenous heating of reaction mixture, lower consumption of organic solvent and drastic reduction in polymerization time, obtaining, in the same time, high molecular weight polymers.",

AB  - Zbog sve veće brige stručne i naučne javnosti o zaštiti životne sredine došlo je do upotrebe ekološki prihvatljivih inhibitora za zaštitu metala od korozije. U ovom radu izvršeno je ispitivanje zaštite bakra obradom korozione sredine primenom različitih koncentracija ekstrakta žalfije 0.5g/dm3,1 g/dm3 i 1.5g/dm3, kao zelenog inhibitora, u rastvoru 3% NaCl. Merenja su izvedena gravimetrijskom metodom i elektrohemijskim metodama (Tafelovom metodom ekstrapolacije i spektroskopijom elektrohemijske impedanse). Najveće dostignute vrednosti zaštitnog faktora ekstrakta žalfije su 60,04% u rastvoru 3%NaCl + 1 g/dm3 i 53% u rastvoru 3%NaCl + 1,5 g/dm3 u vremenskom intervalu od 6 sati. Međutim, isti rastvori u vremenskom intervalu od 4 i 24 h deluju katalitički na proces korozije bakra, te se ekstrakt žalfije ne može preporučiti kao inhibitor korozije bakra u 3%NaCl. Rezultati dobijeni spektroskopijom elektrohemijske impedanse i rezultati dobijeni sa snimljenih Tafelovih polarizacionih dijagrama potvrđuju rezultate dobijene gravimetrijskom metodom, te se mogu preporučiti kao vrlo pouzdane metode za brza koroziona ispitivanja.
AB  - Due to the increasing concern of experts and scientists on environmental protection use of environmentally friendly corrosion inhibitors for metal protection gains more interest. In this paper, research on copper protection by processing corrosive environment while applying different concentrations of sage extract of 0.5g/dm3,1 g/dm3 i 1.5g/dm3 as green inhibitor in 3% NaCl solution was performed. Measurements were carried out by gravimetric method and electrochemical methods (Tafel extrapolation method and electrochemical impedance spectroscopy). The greatest protective values of sage extract of 60,04% were reached in 3%NaCl + 1 g/dm3 solution and 53% 3%NaCl + 1,5 g/dm3 solution in 6 hours interval. However, the same solutions act catalytically on copper corrosion process during time interval from 4 to 24 hours, that is why sage extract can not be recommended as inhibitor of copper corrosion in 3%NaCl. The results obtained by electrochemical impedance spectroscopy and recorded Tafel polarization diagrams, confirm results attained by gravimetric method, thus can be recommended as very reliable methods for quick corrosion tests.

AB  - The parameters of foam preparation, such as addition of fillers, have a significant effect on the properties of polyurethane foams. The goal of this work was to study the effect of the cement addition on the thermo-mechanical properties of rigid polyurethane foams. Isocyanate component was based on polymeric diphenylmethane diisocyanate, and polyol component was polyether type, with addition of castor oil as polyol. It was estimated that the addition of cement increased the values of foam compressive strength and permanent deformation. Compressive strength increased even more than 90% with 20 wt% of cement. Further increase of the cement loading deteriorates the mechanical properties of foamed material because it distorts cellular structures of obtained materials. Addition of cement increased the value of the glass transition temperature of polyurethane foam. The highest increase in the value of glass transition temperature, for 7.5ºC, was achieved by the addition of 20 wt% of cement.

AB  - The paper shows an example of performed optimization of sizes in terms of welding costs in a characteristic loaded welded joint. Hence, in the first stage, the variables and constant parameters are defined, and mathematical shape of the optimization function is determined. The following stage of the procedure defines and places the most important constraint functions that limit the design of structures, that the technologist and the designer should take into account. Subsequently, a mathematical optimization model of the problem is derived, that is efficiently solved by a proposed method of geometric programming. Further, a mathematically based thorough optimization algorithm is developed of the proposed method, with a main set of equations defining the problem that are valid under certain conditions. Thus, the primary task of optimization is reduced to the dual task through a corresponding function, which is easier to solve than the primary task of the optimized objective function. The main reason for this is a derived set of linear equations. Apparently, a correlation is used between the optimal primary vector that minimizes the objective function and the dual vector that maximizes the dual function. The method is illustrated on a computational practical example with a different number of constraint functions. It is shown that for the case of a lower level of complexity, a solution is reached through an appropriate maximization of the dual function by mathematical analysis and differential calculus.

AB  - Using cheap renewable raw materials such as lignocellulosic feedstock for hydrogen production by fermentation has great significance and potential to give a major contribution to future clean energy. Using hydrogen as a promising alternative energy source for fossil fuels is increasing. Hydrogen is clean, renewable high energy fuel that does not contribute the greenhouse gas effect. The main challenges in developing hydrogen production are the low hydrogen yields due to poor efficiency on a direct microbial assimilation of cellulosic materials. From this reason, in the world today occurs considerable research efforts to improve the pretreatment and hydrolysis of lignocellulosic materials. The development of effective cellulase enzymes, optimization and improvement of the fermentation process as well as engineering approaches to application processes are the basis of the increased popularity of the lignocellulosic feedstock. Research on the genomic combined with genetic engineering offers a wide range of opportunities to improve the performance of using cellulosic raw materials in the production of hydrogen. This paper provides an overview of key technologies in the world today that research and development biohydrogen from lignocellulosic feedstocks.

AB  - The subject of the research is influence of sulfuric acid on morphology of electrochemically obtained copper powder during galvanostatic electrolysis mode. In this paper electrodeposition of copper powder from sulphate electrolyte was carried out. Electrolytes with three different concentrations of Cu2+ (7 g/dm3, 18 g/dm3 and 33 g/dm3) were used, each in combination with three different concentrations of H2SO4 (100 g/dm3, 150 g/dm3 and 200 g/dm3), so that copper powder was deposited from nine electrolytes. Copper wire with surface area of 1cm2 was used as cathode, and copper anode in the form of metal sheet was pressed against the wall of electrochemical cell that had volume of 500 cm³. Experiments were carried out at room temperature, and electrolyte stirring was performed using a magnetic stirrer. Copper powder was deposited galvanostatically at current densities of j = 1500 A/m2, j=2000 A/m2 and j=2500 A/m2. Produced copper powder was removed from cathode every three minutes. All the characteristics of powder depend on the size and shape (morphology) of particles and they are mutually correlated. Research of morphology and size of particle was carried out using scanning electron microscopy (SEM). Increase of H2SO4 concentration causes increase in branching of copper powder. It was concluded that the size of copper powder grains reduces with the increase in concentration of H2SO4.
AB  - Predmet istraživanja je uticaj sumporne kiseline na morfologiju elektrohemijski dobijenog bakarnog praha pri galvanostatskom režimu elektrolize. U ovom radu je vršeno elektrohemijsko taloženje bakarnog praha iz sulfatnih elektrolita. Korišćeni su elektroliti sa tri koncentracije Cu2+ (7 g/dm3, 18 g/dm3 i 33 g/dm3) i svaka u kombinaciji sa tri koncentracije H2SO4 (100 g/dm3, 150 g/dm3 i 200 g/dm3), tako da je bakarni prah taložen iz devet elektrolita. Kao katoda je korišćena bakarna žica površine 1cm2, a bakarna anoda u obliku lima je bila priljubljena uz zid elektrohemijske ćelije, zapremine 500 cm³. Eksperimenti su izvođeni na sobnoj temperaturi, a mešanje elektrolita vršeno je pomoću magnetne mešalice. Bakarni prah taložen je galvanostatski pri gustinama struje od: j=1500 A/m2, j=2000 A/m2 i j=2500 A/m2. Proizvedeni bakarni prah je uklanjan sa katode svaka tri minuta. Sve osobine praha zavise od oblika i dimenzija čestica (morfologije) i međusobno su povezane. Ispitivanje morfologije i veličine čestica vršeno je pomoću skenirajuće elektronske mikroskopije (SEM). Sa povećanjem koncentracije H2SO4, povećava se i razgranatost bakarnog praha. Utvrđeno je da se veličina čestica smanjuje sa povećanjem koncentracije H2SO4.

AB  - Solvent base oils of group API I contain larger quantities of aromatic compounds and sulfur, as compared to base oils of higher quality groups. Processing of base oils by commercial clays is performed in order to reduce the content of undesirable compounds, improving the color and oxidation stability. Commercial clays are based on aluminosilicates with a large specific surface area and developed porosity. Bentonite has good adsorption characteristics, which can be further improved by various methods of modification. In this paper, adsorption processing of solvent base oils is derived by acid-activated bentonite and commercial clay. The structural composition of starting oil and refined solvent oil (content of aromatics, paraffins, naphtenes and sulfur) is determined by following methods: IEC 590, UV, IP 346 and BAS ISO 20846. The results showed that processing of a solvent oil by activated bentonite leads to change of structural composition, similar to a change achived by processing with commercial clay.

AB  - Kod poluidealnog gasa, promena entropije ne može se odrediti preko srednjeg specifičnog toplotnog kapaciteta na način kao što se određuje promena unutrašnje energije i entalpije, odnosno razmenjena količina toplote. Uzimajući ovo u obzir, u radu je izveden pogodan model preko koga je moguće odrediti promenu specifične entropije poluidealnog gasa za proizvoljan temperaturski interval primenom tablične metode, koristeći srednje vrednosti razlomljenih temperaturnih funkcija.  Ideja je da se integriranje koje se ovde neminovno javlja, zameni srednjim vrednostima prethodnih funkcija. Model je izveden na bazi funkcionalne zavisnosti stvarnog specifičnog toplotnog kapaciteta od temperature. Pri ovome korišćena je teorema o srednjoj vrednosti funkcije kao i matematičke osobine određenog integrala. 
Srednja vrednost razlomljene funkcije određena je direktno preko njene podintegralne funkcije. Izvedene relacije, primenom računarskog programa, omogućile su sastavljanje odgovarajućih termodinamičkih tablica preko kojih je moguće odrediti promenu entropije proizvoljne promene stanja na efikasan odnosno racionalan način bez primene integralnog računa, odnosno gotovih obrazaca. Na ovaj način, promena entropije poluidealnog gasa, određena je za proizvoljan temperaturski interval analognom metodom koja se primenjuje i kod određivanja promene unutrašnje energije i entalpije odnosno razmenjene količine toplote, što je bio i cilj rada.  Verifikacija predložene metode za gore navedenu funkciju, izvedena je za određeni poluidealni gas za tri usvojena temperaturska intervala, za karakterističnu promenu stanja. Pri ovome izvršeno je poređenje rezultata prema klasičnoj integralnoj i predloženoj metodi preko sastavljenih tablica.Prikazanu metodu, u određenim odnosno posebnim slučajevima, moguće je primeniti i kod određivanja promene entropije realnog gasa.Isto tako, u radu je pokazano da je promenu entropije za posmatrani karakterističan slučaj, moguće predstaviti odnosno grafički odrediti planimetrijskom metodom u dijagramima sa pogodno odabranim koordinatama.

AB  - U ovom radu, koristeći postojeća znanja iz termodinamike,  prikazana su tri načina grafičkog određivanja eksponenta politrope, kao i klasični analitički način.U radu smo koristili karakteristične dijagrame p-v i T-s i u njima konstruisali određene politropske promene koje smo u daljim razmatranjima koristili za određivanja eksponenta politrope. Prvi način se zasniva na konstruisanju dijagrama log p=f(log v) i iz nagiba prave očitavamo vrednost traženog eksponenta. Druginačin je nešto složeniji i zasniva se na konstruisanju politrope u p-v dijagramu, na koju, u proizvoljnoj tački politrope, povlačimo tangentu i diferencijalnom metodom dolazimo do eksponenta politrope. A treći način zasniva se na konstruisanju politrope u T-s dijagramu, korišćenju osnovnih teorema diferencijalnog računa, odnosno I i II zakona termodinamike za uočene izotermske promene i pisanju osnovne jednačine politropske zavisnosti u diferencijalnom obliku. Prikazana grafička rešenja omogućuju efikasnijije teorijsko izučavanje politropskih promena stanja i znatno pomažu jasnijiem sagledavanju problema koji su u vezi sa ovom vrstom promene stanja.

AB  - In this paper, for the case of isothermal quasi static characteristic change of the state of real gas is given graphical representation respectively determination of the most important energy values in h-s and T-s diagrams. At present, by using the fundamental theorem of differential calculus, the first and second law of thermodynamics is written in differential form, dependence is derived that allowed precise graphic design to determine the most important values of the process (technical work and amount of exchanged heat) to h-s diagram, over certain straight lines which represent the height differences. Performed graphic design, is applied to two typical cases in the same diagram. Also, a comparison is performed with same change of state in the case of an ideal gas. In the second part of this paper, starting from the fact that for the behavior of real gas, co-ordinate systems h, s and T, s are suitable but p, v systems, the proposal is given to the graphic representation of the changes of enthalpy and internal energy in heat T-s diagram. In this case, it is used the lines of constant enthalpy and internal energy i. e. that is their point of intersection with isobars, which passing through the endpoint of analyzed the change of state. It is shown that the change of enthalpy and internal energy in T-s diagram can be presented planimetry over the appropriate areas. Based on the certain change of enthalpy and internal energy, by using the both form of the first law in thermodynamic, it is shown that in addition to the amount of ex- changed heat, but it is possible for volume and technical work, for the proposed change of state of real gas, also can be represented graphically in T-s diagram, over suitable equivalent areas, which was the basic idea of this paper. Displayed graphics solutions in relation to the analytical solutions allows more efficient theoretical study of thermodynamic process which is observed from different points, they significantly assist for clear understanding of the problem and improve of mutual understanding.

Koristeći osnovnu teoremu diferencijalnog računa, odnosno I i II zakon termodinamike napisan u diferencijalnom obliku, izvedena je opšta zavisnost koja je omogućila preciznu grafičku konstrukciju za određivanje najvažnijih veličina procesa (tehnički rad i razmjenjena količina toplote) u h-s dijagramu, preko odgovarajućih duži koje predstavljaju visinske razlike. Izvedena grafička konstrukcija, primjenjena je na dva karakteristična slučaja u istom dijagramu. Prethodno je izvršeno i poređenje sa istom promenom stanja za slučaj idealnog gasa. U drugom delu rada, polazeći od činjenice da su za prikazivanje promena stanja realnog gasa mnogo pogodniji koordinatni sistemi h, s i T, s nego p, v sistem, dat je predlog za grafičko predstavljanje promene entalpije i unutrašnje energije u toplotnom T-s dijagramu.

AB  - In the thermodynamics practice, both for semi – ideal and for real gases, the
dependence of the middle specific heat capacity of temperature, is usually determined by experimentally as linear function, mainly, for the relatively short temperature range. In addition to this, for the purpose of various analyzes, both in theory
and in practice, is necessary to know the dependence of the real specific heat capacity of temperature also. Due to this, in this paper was the definition of the middle specific heat capacity for certain, selected a suitable temperature range, by using differential and integral calculus, analytical dependence is derived from the real
specific heat capacity and the middle specific heat capacity. The relation which is
given in the differential form for defined temperature range, allows direct troubleshooting without special restriction on its use. By using the resulting dependence,
the general model is derived in the form of polynomial of arbitrary degree by depending of temperature, which is faster and more convenient for practical application of the current model, which has not a general character. Also the existing
model is not the most appropriate because it solves the problem given indirectly,
considering it requires analytical dependence of the amount of exchanged heat.
Correlation which has derived in this paper, can be effectively applied to obtain of
depending on the amount of exchanged heat between the temperature and also for
the observed temperature range. Derived analytical relation was used to obtain
another relation to the amount of exchanged heat which have a more complex form
of the existing two, which can be applied for various thermodynamic analysis. Verification of the present model and the possibility of its application is given to a
few characteristic examples of semi – ideal and real gas and CO2 gas as semi –
ideal based on the experimental results, the diatomic semi ‒ ideal gases starting
from Einstein relation, water as real fluid starting from the Dieteritium relation,
and at the and characteristic group of real gases. Therefore, it is seen wider temperature range.

AB  - This paper analyzes the catalytic effect of sulphuric acid on current efficiency, the coating thickness and the rate of deposition of electrochemical chromium coatings. According to the properties of chrome, there are three types of chrome coatings: decorative, hard and porous. The quantitative composition of baths and working conditions are the factors which determine which type of a coating will be obtained. The cathodes are made of copper electrolitical plates (99.99%), which are submitted to mechanical smoothing and chemical preparation. Electrochemical chromium coatings were deposited galvanostaticaly from bath I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), are then deposited on the cathodes prepared in this way, also from bath II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), and from bath III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), at current densities of 10 A/dm2, 15 A/dm2 and 30 A/dm2. Deposition was performed for 5, 10 and 15 minutes intervals in all three baths and for all three current densities. The difference in samples mass before and after electrochemical deposition was measured on the analytical scale. Cathodic current efficiency, the coating thickness and deposition rate increase with the increase of acid concentration, current density and deposition time. The average deposition rates are approximately the same for baths II and III, for the same deposition time, at the same current densities. This shows that the increase of the concentration of sulphuric acid above 2.5 g/dm3 is not justifiable. The ratio of these parametres, according to the quantity of the sulphuric acid used is the best for bath II, which makes deposition of electrochemical chrome coatings from this bath most profitable, from the aspect of current efficiency, deposition rate, coatings quality and chemicals consumption of bath.
AB  - Ispitivan je katalitički uticaj sumporne kiseline na iskorišćenje struje, debljinu i brzinu taloženja prevlaka hroma dobijenih elektrohemijskim putem. Zahvaljujući osobinama hroma razlikuju se tri vrste prevlaka: dekorativne, tvrde i porozne. Kvantitativni sastav kupatila i radni uslovi su faktori koji određuju koji tip prevlaka će biti dobijen. Katode su bile od tehničkog bakra nepoznatog sastava, koje su mehanički glačane pa zatim hemijski pripremljene. Za elektrohemijsko taloženje prevlaka hroma, koje su taložene galvanostatski, ispitivana su tri elektrolita čiji se kvantitativni sastav razlikuje u koncentraciji sumporne kiseline, dok je koncentracija CrO3 bila ista u sva tri kupatila i to: kupatilo I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), zatim kupatilo II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), i na kraju kupatilo III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), pri gustinama struje 10 A/dm2, 15 A/dm2 i 30 A/dm2. Katodno iskorišćenje struje, debljina prevlaka i brzina taloženja se povećava sa povećanjem koncentracije sumporne kiseline, gustine struje taloženja i vremena taloženja. Srednje brzine taloženja prevlaka hroma su približno iste za kupatila II i III, pri istim vremenima taloženja i pri istim gustinama struje. S tim u vezi, povećanje koncentracije sumporne kiseline iznad 2,5 g/dm3 nije opravdano. Odnos ovih parametara, prema koncentraciji sumporne kiseline, je najbolji za kupatiko II, koje daje optimalne prevlake hroma dobijene elektrohemijskim putem, u pogledu iskorišćenja struje, brzine taloženja, kvalitata prevlake i hemijskog sastava kupatila.

Srednje brzine taloženja prevlaka hroma su približno iste za kupatila II i III, pri istim vremenima taloženja i pri istim gustinama struje. S tim u vezi, povećanje koncentracije sumporne kiseline iznad 2,5 g/dm3 nije opravdano. Odnos ovih parametara, prema koncentraciji sumporne kiseline, je najbolji za kupatiko II, koje daje optimalne prevlake hroma dobijene elektrohemijskim putem, u pogledu iskorišćenja struje, brzine taloženja, kvalitata prevlake i hemijskog sastava kupatila.",
