AB  - The aim of the article is to show the effects of the main air plasma gasifier operating parameters, such as temperature and equivalence ratio on the gasification performance of sewage sludge from wastewater treatment plants. The parametric study was performed using a one-dimensional mathematical model to determine the equilibrium composition of the system. The model is based on the principle of the minimum of the Gibbs function and uses only the ultimate and proximate analysis data as input to the model. The output of the model gives the equilibrium composition of the gasses produced. The parametric analysis was performed in order to determine the optimal operating parameters of the plasma reactor in order to obtain syngas with the highest heat value while achieving the maximum efficiency of the process. The collected results can be useful in further analysis of the gasification processes in plasma reactor, such as exergy analysis and kinetics.

AB  - Biomass is considered as an important renewable resource, which plays a key role in the  development of sustainable energy systems. Biomass can be converted into energy or valuable  chemicals by combustion, liquefaction, pyrolysis and gasification. Among these processes, thermal  gasification “decomposes” biomass into the light chemical species at high temperatures, which can  be applied to biomass with the greatest diversity. As the final (target) product of biomass gasification,  syngas or gas rich in hydrogen (H2), are very important intermediate products in the petrochemical  industry. However, the problematic tar produced during gasification could bring a number of  problems. Catalytic biomass gasification is a promising strategy to significantly alleviate these  problems. Transition metal-based catalysts for catalytic biomass gasification have been studied in  recent decades. This review discusses various transition metal catalysts for biomass gasification,  including nickel (Ni)-based monometallic and bimetallic catalysts and other Fe- and Pt-based  catalysts. The performance of these catalysts is evaluated based on the applied reaction parameters,  the quality of the syngas produced, and the tar reduction performance. Applications of DFT (‛Density  Functional Theory’) calculations and AI (‛Artificial Intelligence’) to study biomass gasification  mechanisms are summarized, and the cause of catalyst deactivation and regeneration of spent  catalysts are also discussed. Likewise, in this review, the development potential of catalytic  gasification of biomass in the Republic of Serbia was considered.

AB  - The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS techniques, through chemical exergy analysis. In addition to considering the physical and chemical characteristics of given feedstocks for their efficient thermo-chemical conversion into pyrolytic gas, in this study, a theoretical simulation for their implementation use in the gasification process was also performed. The performed thermodynamic study with detailed exergy analysis showed that the large contribution of exergy in syngas components such as CO and H2 originates primarily from cellulose pyrolysis of EC-1, while large exergy contribution in syngas component as CH4 originates from lignin pyrolysis of EC-2. It was founded that the exergy efficiency of syngas for EC-1 equals 19.04%, which is lower than the exergy efficiency of syngas for EC-2 (20.46%), as a result of higher ash content in EC-1. Also, it was reported that higher carbon (C) and hydrogen (H) contents present in the EC-2 sample generate higher gaseous energy and exergy values, i.e. the increment of exergy efficiency of syngas, by both approaches (pyrolysis and gasification exergy analysis), but results in a lower biomass chemical exergy (18.28 MJ kg−1). The methodology applied to the gasification process was shown a higher exergy efficiency for EC-2 (∼36 – 42%) than for EC-1 (∼33 – 39%), dependant on the equivalence ratio (ER).

AB  - This work provides insight into possibilities of maximum utilization of C3-C4 energy crops for thermo-chemical conversion (slow pyrolysis) into high value biochemicals, platform chemicals, drop-in fuels and combustible gases, using coupled kinetic and thermodynamic analyses. In order to examine the kinetics of decomposition of lignocellulosic components, model-free and model-based methods faded from thermal analysis data were used. Thermodynamic compensation was used for explicatory of entropy controlled process, where conformational changes and chemical exchange directly affect the type and distribution of obtained pyrolytic products. It was shown that external variable (i.e. the heating rate/temperature) does not change either an entire reaction mechanism (mechanistic nature of MG and AD pyrolyses) or transition state, but it changes activation enthalpy and activation entropy which lead to differences in terms of heat energy consumption, pyrolysis favorability and thus rates of generation of activated complex among feedstocks. To investigate the interplay of catalysts (present in feedstocks as minerals) and reactants, selective energy transfer (SET) model was applied. The model showed an activity of catalyst with different outputs towards two reactants, lignin part of the structure in MG and 1,8-cineole in AD. It was shown that AD is more convenient for thermal conversion than MG, regarding to lower transformation energy requirement, higher reactivity, as well as much faster accumulation of products.

AB  - The development of carbon materials with desirable textures and new aqueous electrolytes is the key strategy to improve the performance of supercapacitors. Herein, a deep eutectic solvent (DES) was used for in situ templating of a carbon material. A carbon material was characterized (XRD, N2-physisorption, FTIR, SEM and EDS) and used as an electrode material for the first time in multivalent-based supercapacitors. In situ templating of carbon was performed using a novel DES, which serves as a precursor for carbon and for in situ generation of MgO. The generation of MgO and its roles in templating of carbon were discussed. Templating of carbon with MgO lead to an increase in surface area and a microporous texture. The obtained carbon was tested in multivalent-ion (Al3+ and Mg2+) electrolytes and compared with H2SO4. The charge-storage mechanism was investigated and elaborated. The highest specific capacitance was obtained for the Al(NO3)3 electrolyte, while the operating voltage follows the order: Mg(NO3)2 > Al(NO3)3 > H2SO4. Electrical double-layer capacitance (versus pseudocapacitance) was dominant in all investigated electrolytes. The larger operating voltage in multivalent electrolytes is a consequence of the lower fraction of free water, which suppresses hydrogen evolution (when compared with H2SO4). The GCD was experimentally performed on the Al(NO3)3 electrolyte, which showed good cyclic stability, with an energy density of 22.3 Wh kg−1 at 65 W kg−1.

AB  - In this work, plane tree seed-based activated carbons were characterized in detail for a variety of applications. The particularly important area of application would be in the artificial photosynthesis. After carbonization process of biomass precursor at 650°C, the resulting preliminary activated carbons were activated at various temperatures. The activated carbons were characterized by oxygen functionalities (a particularly important role has ester oxygen groups) which provide a unique microstructure. The chemical compositions of as-prepared activated carbons were analyzed through Fourier transform infrared and Raman spectra as well as gas chromatography–mass spectroscopy analysis, while morphology was observed by scanning electron microscopy analysis. Applied analysis showed that detected graphite mainly becomes uniformly nanocrystalline system. The current study also explored the applicability of carbon material obtained from plane tree seed as a potential gaseous adsorbent. The characterization showed that the tested material contains both mesopores and micropores, and this should be advantageous for the gas sorption process, since mesopores may provide low-resistant pathways for the diffusion of CO2 molecules, while the micropores are the most suitable for trapping of CO2. The sorption process analysis (including adsorption/desorption isotherms behavior) shows indication that the rate-limiting step of CO2 adsorption onto activated carbon is probably governed by diffusion-controlled process, especially at temperatures below 850°C.

AB  - The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) would allow creation of highly porous and spatially distinct ordered bio-SiC ceramics. The results of carbonization experiments at several operating temperatures and activation of carbons with multiple-cycle treatments TEOS clearly showed the possibility of obtaining SiC nano-structures, after performing the carbothermal reduction at 1400 °C. The increase in the activation temperature and the duration time starts the development of the SiC particles inside the porous structure. The XRPD analysis showed that the major SiC polytype has cubic SiC (β-SiC) structure and remainder is hexagonal SiC polytypic (α-SiC) structure. It was established that the carbons obtained from carbonization of the Platanus orientalis L. plane tree fruit (PTF) precursor and activated at 850 °C with longer holding times (1 and 2 h) exhibit β-SiC (cubic) nano-wires. A possible nano-wires increment mechanism was suggested. The obtained results represent significant contribution in understanding the process as well as the main characteristics of SiC nano-materials and their possible applications.

AB  - U radu je prikazana skrining metoda određivanja ukupne alfa i beta aktivnosti u uzorcima glina. Merenja su obavljena na niskofonskom gasnom proporcionalnom brojaču. Takođe je prikazan i uticaj datih glina na oscilatornu Briggs-Rauscher reakciju. Briggs-Rauscher (BR) reakcija je oscilatorna reakcija, u kojoj je oksidacija malonske kiseline (CH2(COOH)2) u prisustvu vodonik peroksida (H2O2) i kalijum jodata (KIO3), katalizovana jonom mangana (Mn2+) u kiseloj (HClO4) sredini. Ova reakcija se uspešno koristi kao matriks za određivanje koncentracije analita, kao i njihove potencijalne antioksidativne/antiradikalske aktivnosti. U ovom radu, po prvi put je upotrebljen BR reakcioni sistem kao medijum za ispitivanje različitih vrsta glina.
