Abstract In this paper we are reporting the preparation and characterization of supported cobalt catalysts using a wetness impregnation method. Different cobalt catalysts loading of 0 and 10 wt% were prepared by dissolving cobalt nitrate hexahydrate in distilled water and … Continue reading →

Abstract: In order to improve the efficiency of biodiesel production from esterification of free fatty acids, an alternative to sulfuric acid has been explored. In this study, esterification of oleic acid was performed using 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIM][HSO4]) ionic liquid … Continue reading →

Abstract: The catalytic ozonation of sulfamethoxazole was investigated in this study using response surface methodology. The effect of four parameters pH of solution, concentration of antibiotic, ozone concentration and circulation rates was investigated on removal of sulfamethoxazole and COD of … Continue reading →

Abstract: The catalytic conversion of lignocellulosic biomass to levulinic acid in ionic liquid, [EMIM][Cl] was conducted using a hybrid catalyst. The hybrid catalyst (1:1 ratio) with equal CrCl3 and HY zeolite weight ratios was synthesized using a wet impregnation method. … Continue reading →

Abstract: This study is aimed at investigating the interactive effect of reaction variables on the composition and octane number of reformat in catalytic naphtha reforming gasoline fuel. The relationship between aromatization activity and RON, with three reaction variables, namely temperature … Continue reading →

Abstract: In this study, a microchannel monolith photoreactor was investigated for photocatalytic CO2 reduction with H2O in gaseous phase using TiO2 and indium doped TiO2 nanoparticles. Effects of operating parameters such as monolith geometry, reaction temperature, indium loading and feed ratios were investigated … Continue reading →

Abstract: Solar conversion of CO2 to hydrocarbon fuels seems promising to reduce global warming for improved sustainability. Solar energy, as direct solar irradiations, is excessively available and it is imperious to utilize it for solar fuel production. This review paper is … Continue reading →

Abstract: In this study, the performance of a montmorillonite (MMT)/TiO2 coated monolith photoreactor was tested for the photocatalytic CO2 reduction. CH4 and CO were the main products having yield rates of 139 and 52 μmole g catal.−1 h−1, respectively. The other adequately significant products were C2H4, C2H6, … Continue reading →

Abstract: Response surface methodology (RSM) has been used to optimize the effect of circulation rates, ozone supply, cephalexin (CEX) concentration, and granular activated carbon (GAC) dose on removal of COD from solution. According to statistical analysis, all of the input … Continue reading →

Abstract: Montmorillonite (MMT) modified TiO2 nanocomposites were synthesized by single step sol–gel method. The samples were characterized by XRD, FE-SEM, HR-TEM, FT-IR, N2-adsorption–desorption, UV–vis and photoluminescence (PL) spectroscopy. Modification of TiO2 with MMT controlled the crystal growth and produced anatase phase of … Continue reading →
