AB  - U okviru ove doktorske disertacije ispitivana je mogućnost sinteze aktivnog niklenog  katalizatora modifikovanog magnezijumom u reakciji hidrogenizacije suncokretovog ulja,  upotrebom perlita kao nosača katalizatora. Da bi se ispitala moguća aktivacija odabranog perlitnog  nosača (PF-295), on je tretiran u destilovanoj vodi na 90 °C, u 10 % rastvoru Na2CO3 na 90 °C i u 9 mol/dm3 HCl-u uz refluks na 100 °C. Karakterizacijom nosača nisu uočene značajne razlike u  morfologiji, teksturi i strukturi dobijenih materijala. Za sintezu prekursora na različito tretiranim nosačima korišćen je precipitacionodepozicioni postupak, upotrebom čvrstog Na2CO3 kao taložnog agensa nikl (nNi:nSiO2 = 1) i  magnezijum (nMg:nNi = 0,1) vrsta. Rezultati karakterizacija prekursora su pokazali da među njima  ne postoje značajne razlike, osim u vrednostima disperznosti (određene hemisorpcijom H2). Takođe  su uočene manje razlike u aktivnosti sintetisanih katalizatora u katalitičkim testovima hidrogenizacije suncokretovog ulja. Upotrebom različitih molskih odnosa (nNi:nSiO2 i nMg:nNi) dobijene su dve serije prekursora  koje su okarakterisane morfološki, teksturalno i strukturno. Prekursori serije sa različitim sadržajem  Ni pokazali su razlike u rezultatima svih karakterizacionih tehnika, a ove razlike su bile još  izraženije kod serije sa različitim sadržajem Mg, naročito vrednosti disperznosti Ni0 . Primenom  različitih temperatura redukcije (270 °C, 300 °C, 330 °C, 360 °C i 460 °C) i određivanjem vrednosti  disperzije Ni0 redukovanih prekursora, utvrđen je optimalni molski odnos nNi:nSiO2 . Optimalna temperatura redukcije ovog prekursora (nNi:nSiO2 = 0,25) određena je na osnovu rezultata katalitičkih  testova parcijalne hidrogenizacije suncokretovog ulja. Na ovoj temperaturi (345 °C) su redukovani  svi prekursori i ispitani su u katalitičkim testovima, nakon čega je određivan sadržaj masnih kiselina parcijalno hidrogenizovanog suncokretovog ulja gasno-hromatografskom analizom. Utvrđeno je da  najveću aktivnost pokazuje katalizator sa molskim odnosom nNi:nSiO2 = 0,25 i nMg:nNi = 0,1. Ovim je  pokazano da je moguće sintetisati aktivni nikleni katalizator za hidrogenizaciju suncokretovog ulja  upotrebom perlita kao nosača i magnezijuma kao promotora.
AB  - Within the scope of this doctoral dissertation, the synthesis of a nickel catalyst modified  with magnesium on perlite as support for the process of hydrogenation of sunflower oil was  investigated. To examine the possible activation of the selected perlite support (PF-295), it was  treated in distilled water at 90 °C, in 10% solution of Na2CO3 at 90 °C and in 9 mol/dm3 HCl with  reflux at 100 °C. No significant differences in the morphology, texture or structure of the obtained  materials were observed. For precursor synthesis, precipitation-deposition method was used with solid Na2CO3 as a  precipitating agent of nickel (nNi:nSiO2 = 1) and magnesium (nMg:nNi = 0.1) species. Synthesis of  Ni2+ precursors on various supports, using Mg as a modifier, no significant differences in the  synthesized precursors were also shown, exept the differences observed in the dispersion values  (measured by chemisorption of H2). Minor differences in the activity of afterwards synthesized  catalysts were observed in catalytic tests of the hydrogenation of sunflower oil. Variation of the values of two synthesis parameters (nNi:nSiO2 and nMg:nNi) yielded a series of  precursors, later characterized by morphological, textural and structural techniques. For different Ni  contents, precursors showed an obvious difference in their characterization, while differences in  characterization, especially in Ni0 dispersion, were were more obvious for different Mg contents in  precursors. Measuring the dispersion of Ni0 at different temperatures (270 °C, 300 °C, 330 °C, 360  °C and 460 °C), the optimal molar ratio of nNi:nSiO2 was obtained. Optimal reduction temperature of  this precursor (nNi:nSiO2 = 0.25) was established by their catalytic activity in partial hydrogenation  of sunflower oil. At this temperature (345 °C), all precursors were reduced and tested in catalytic  hydrogenation of sunflower oil, after which fatty acid composition was determined by gas  chromatography. The catalyst with the molar ratio nNi:nSiO2 = 0.25 and nMg:nNi = 0.1 showed the  highest activity. With this it was shown that it is possible to synthesize an active nickel catalyst for  the hydrogenation of sunflower oil using perlite as support and magnesium as promotor.

AB  - Use of broken honeycomb-like expanded perlite as support for magnesium modified nickel catalysts in process of partial hydrogenation of sunflower oil was studied. By the use of the precipitation-deposition method, two groups of precursors were synthesized: different Ni/SiO2 mole ratios with constant Mg/Ni mole ratio 0.1, and different Mg/Ni mole ratios with constant Ni/SiO2 mole ratio 0.25. Characterizations of precursors were done (scanning electron microscopy, diffuse reflectance UV–Vis, infrared spectroscopy, N2-physisorption, temperature programmed reduction (TPR) and He-pycnometry) to determine the material differences, considering the change in morphology, structure, texture and reducibility with overall Ni and Mg content. In addition, TPR and hydrogen chemisorption were performed in order to estimate the temperature reduction range of supported precursors and the dispersion degree of nickel in reduced precursors, respectively. The interaction between Ni2+ and perlite support was established. Different reducibility and dispersion were obtained as a function of Ni/SiO2 and Mg/Ni mole ratios. After the precursor’s reduction and paraffin oil impregnation, the obtained catalysts were tested in a sunflower oil hydrogenation reaction. Catalyst activity was monitored through the decrease of the refractive index and hydrogen consumption that gave the insight that the influence on catalyst activity represents the accessibility of triacylglycerols and not always the hydrogen determined dispersion degree

AB  - Mg-doped co-precipitated Ni/SIG precursors were studied as edible sunflower oil hydrogenation catalysts applying two types of commercial silica gels (SIG) as supports of different texture characteristics: a microporous type (SIG-A) and a mesoporous type (SIG-C). It was found that texture parameters of both the silica gels and magnesium addition allow obtaining of catalysts of various hydrogenation activities and fatty acid composition of the products. The results reveal the highest hydrogenation activity of MgNi/SIG-C catalyst because of higher amount and accessibility of metal nickel particles on the catalyst surface generated through reduction procedure. A dominant activity of MgNi/SIG-C catalyst is ascribed to appropriate mesoporosity, which controls diffusion. It was established that Mg-doped Ni/SIG-C possessed a capacity for use as an efficient edible vegetable oil hydrogenation catalyst due to high hydrogenation activity, high saturation level of linoleic acid (C18:2cis), moderate amounts of C18:1trans fatty acids, and C18:0 stearin acid formation in the partially hydrogenated sunflower oil.

AB  - The simultaneous photocatalytic degradation of two dyes: methylene blue (MB), a cationic dye, and arylazo pyridone dye (SD), an anionic dye was investigated using sol-gel prepared TiO2 particles. The paper shows the main difference in degradation kinetics between single dye solution and binary dye solutions. The effects of competitive adsorption and the concentration of the dyes on degradation rate were analyzed. The preferential adsorption capacity of TiO2 toward MB was attributed to electrostatic interactions between the cationic dye and negatively charged TiO2 surface, while repulsion between the negatively charged surface of the catalyst and SD dye results in its lower adsorption capacity. The TiO2 surface charge and accordingly adsorption affinity of investigated dyes were found to be the main factors affecting degradation rate of the dyes. In the single dye system, the catalyst showed considerably higher degradation activity toward MB than to SD. In binary dye systems, the presence of SD did not affect the degradation of MB. On the other hand, the degradation efficiency of SD was found to be highly influenced by initial MB concentration and absorption ability of MB. In addition, higher MB concentration induces the production of a higher amount of reaction products, which also determine the SD degradation rate. Three kinetic regimes for the photodegradation of SD in binary mixtures were observed, used as a starting point to elucidate most influencing parameters for SD reaction kinetics.

AB  - This study aims to gain insights in structure-activity relationship of TiO2 photocatalysts. For this purpose photocatalysts were synthesized via classical sol-gel method using titanium isopropoxide as a precursor and polyethylene glycols (PEGs) of different molecular mass (M-n = 200, 600, 2000, 10,000) as a template agents. Incorporating PEG into TiO2 network enhanced not only catalyst porous structure, but also increased the fraction of anatase phase. The use of low-molecular-weight PEGs resulted in catalysts with increased anatase content and enlarged specific surface area. The catalyst photoactivity was estimated through degradation of organic pollutants: Reactive Black 5, arylazo pyridone dye and phenol. The results revealed that the photoactivity was following the same order independently of target pollutant: TiO2/P600 > TiO2/P200 > TiO2/P2000 > TiO2/P10000 > TiO2. BET surface area and anatase fraction, rather than pore diameter or pore volume, were found to be predominant catalyst property determining the activity for particular reaction system. The existence of synergistic effect between anatase and rutile phases was confirmed for the most active catalysts TiO2/P200 and TiO2/P600. These catalysts showed similar activity in dye degradation, while TiO2/P200 displayed significantly lower activity in phenol degradation, which was attributed to its lower sorption capacity and lower UV light utilization. The difference in the reactivity between investigated pollutants was discussed in relationship with their size, structure and sorption ability.

AB  - Sunflower oil hydrogenation process was studied on silica supported nickel catalysts. Three texturally different silica gel materials were used as supports for synthesis of Ni/SiO2 catalyst precursors. After precursors' reduction and paraffin oil impregnation, obtained catalysts were used in sunflower oil hydrogenation reaction. For catalytic test, a new type of catalyst feeder was constructed and presented. The hydrogenation activity of catalysts was monitored through the decrease of refractive index and hydrogen consumption. A correlation between iodine value, refractive index and hydrogen consumption was established. The reaction rate constants were obtained from fatty acid composition of partially hydrogenated oil and further studied for the investigation of possible reaction pathways. Kinetics and mechanisms were evaluated and tested with the aim to reduce the number of reactions participating in the reaction scheme. A set of ordinary differential equations, corresponding to the investigated model, was solved numerically by Gear's algorithm. It was shown that a number of significant reactions in a model depend on the activity of catalysts. More active catalyst results in more reaction pathways and more side chemical reactions.

AB  - Investigation was conducted in order to elucidate the possibility of using perlite as support for preparation of nickel based precursor catalyst, potentially applicable in vegetable oil hydrogenation process. On three differently prepared expanded perlite, nickel catalyst precursors with identical Ni/SiO2 = 1.1 and Ni/Mg = 10/1 ratios were synthesized by precipitation-deposition method. Different techniques, SEM micrography, He-pycnometry, calcimetry, Hg-porosimetry, N-2-physisorption, H-2-chemisorption and temperature programmed reduction, were used for characterization of obtained samples. Determining the precursor texture, morphology and reducibility shows a successfully deposited nickel phase on perlite support with promising properties for vegetable oil hydrogenation. Chosen precursor was reduced and passivated in paraffin oil and the obtained catalyst showed significant catalytic activity in the test of sunflower oil hydrogenation.

AB  - Diatomite supported nickel catalyst precursors (Ni/D) were prepared by the precipitation-deposition (PD) method using different nickel salts such as nitrate, chloride, acetate and formate. The effect of counter ions (NO3-, Cl-, CH3COO-, and HCOO-) on the texture of prepared samples was studied. For determination of the textural characteristics mercury intrusion porosimetry (MIP) and N2 physisorption techniques were used. MIP and physisorption data (pore volume, pore size distribution, porosity as well as N2 adsorptiondesorption isotherms and BET surface area) showed that counter ions were found to have a profound effect on the microstructure and porosity characteristics of Ni/D precursors. An order of the counter ions effect on the textural characteristics of prepared precursors was determined.
