AB  - Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 aerogel catalysts were synthesized using sol-gel method and supercritical drying in excess solvent, and investigated in the hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl dibenzothiophene (4,6-DMDBT). The influence of supercritical drying on the final catalytic properties of the materials was determined by parallel synthesis of aerogels and xerogels for Re/Pd-TiO2/SiO2 catalysts. The sol-gel method and supercritical drying were found to result in amorphous aerogels with relatively high degree of uniformity, of both supports and active phases. Corresponding xerogels were found to be similar to aerogels in terms of composition and structure, but characterized by lower specific surface areas. Catalytic activity of Co/Mo-Al2O3/SiO2 aerogel catalysts in HDS of DBT and 4,6-DMDBT has shown no major improvement in comparison to conventional Co/Mo catalyst. On the other hand, Re/Pd-TiO2/SiO2 aerogels, obtained with the addition of mesitylene or without it, achieved 70 % and 64 % higher conversion of 4,6-DMDBT than conventional Co/Mo catalyst, respectively. Increased catalytic activity can be attributed to well dispersed Re and Pd active phases across the catalyst structure, good incorporation of Ti within silica matrix, increased mesopore volumes and high specific surface areas.

AB  - This study is based on the application of mathematical methods of statistical analysis that can be used to predict the development of motor fuel consumption in the Republic of Serbia. It is based on the linear dependence of consumption growth of motor fuel from the development of gross domestic product per capita, which is then corrected by introducing five additional influencing parameters. The model results indicate that the total consumption of motor fuels in Serbia from 2010 to 2025 will be increased by 26.5%. Individual consumption of motor fuels shows different market tendencies. Diesel fuel consumption expects to continue intensive growth to 2025, even though slightly slower than the achievements in the last decade. The current trend of declining demand for gasoline will be stopped from 2015-2016, then followed by slow growth of demand by 2025. Consumption of liquefied petroleum gasses (LPG) will enter the phase of saturation in 2015.
AB  - Ovaj rad se bazira na primeni metoda matematičke statističke analize koji mogu da posluže za predviđanje razvoja potrošnje motornih goriva u Republici Srbiji. Model je baziran na linearnoj zavisnosti rasta obima potrošnje motornih goriva od razvoja bruto domaćeg proizvoda po glavi stanovnika koja je potom korigovana uvođenjem pet dodatnih uticajnih parametara. Svakom od ovih parametara dodeljen je odgovarajući koeficijent koji odmerava specifični uticaj istog na potrošnju motornih goriva. Rezultati modela ukazuju da će ukupna potrošnja motornih goriva u Srbiji od 2010. do 2025. biti uvećana za 26,5%, sa 2,36 Mt/god na 2,99 Mt/god. Potrošnju dizel goriva očekuje nastavak intenzivnog rasta, doduše nešto usporen u odnosu na ostvarenja u prethodnoj dekadi i do 2025. potrošnja će dostići nivo od blizu 2 Mt. Postojeći trend opadanja tražnje motornih benzina biće zaustavljen 2015-2016, nakon toga sledi spori rast tražnje i do 2025. potrošnja će biti oko 550 Kt. Potrošnja tečnog naftnog gasa (TNG) nakon intenzivnog rasta od 2015. ući će u fazu saturacije, tako da će u periodu 2010-2025. godine zabeležiti mali porast potrošnje - sa 377 na 435 Kt/god.

AB  - Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods of photolytic, photocatalytic and microbiological degradation of methyl tertiary butyl ether (MTBE) dissolved in wastewaters. The effects of concentrated solar radiation simulated with sodium lamp (SONT UV 400) have been investigated in laboratory experiments. Our result indicated that bacteria Pseudomonas strain CY, isolated from the kerosene, and added alone, was able to gradually degrade MTBE and to decrease its concentration for 93.6% in 12 h. However, the percentage of photolytic degradation decrease in only 4 h was 99.2%. By adding Pseudomonas strain CY after 4 h of light treatment, the degradation was enhanced to 99.55% in additional 5 h. The photocatalytic process was performed in slurry-catalyst reactor with different concentrations of TiO2 catalyst: 5, 0.5 and 0.25 g/L. The MTBE degradation producing carbon dioxide reached 91% in only 150 min, when 5 g/L of catalyst was used.

AB  - The performed investigations were directed toward the analysis of the performance and activity of the fresh and regenerated Cyanamid HDS 20C catalyst in a laboratory batch reactor (2 dm3) for the HDS of the diesel fraction (light gas oil, LGO). Testing of the regenerated catalyst was performed with light gas oil (LGO) of different characteristics. The determined values of the reaction rate constant were compared to some published data in the literature for the HDS of specific sulfur compounds as well as the values of the activation energy. The rates of deactivation of the fresh and regenerated catalyst actually existed compared to some other results recently published in the literature. However, such an observed differences were not sufficient to derive a relation which could be used for the determination of the rate of catalyst deactivation.
