The hydrogenation of carbon dioxide (CO2) to methanol in presence of nanocatalysts has been reported as the one of the most economical and effective ways to reduce CO2 emissions. Over the past several decades, numerous efforts have been made to develop effective catalysts for CO2 hydrogenation to methanol. Among these, the CuO and ZnO based catalysts were highly active for methanol synthesis. Many studies have shown that SBA-15 (Santa Barbara Amorphous or mesoporous silica has good application prospects as a catalyst carrier material because of its flexible pore structure and large specific surface area. In this study ZnO/CuO/SBA-15 catalyst has been synthesized by sol-gel combustion preparation method. Mixing the base composite with kaolinite clay was chosen to enhance the CO2 hydrogenation conversion and to make methanol synthesis more cost-effective. The loading of Cu and Zn were 20.1 wt. % and 2.75 wt. %, respectively. The composite was characterized using XRD analysis, N2 adsorptiondesorption analysis and SEM-EDX analysis. The performance of catalyst was evaluated in a fixed-bed tubular micro-activity reactor at 20 bar with H2 to CO2 molar ratio 3 to 1. The effect of temperature was studied in the range of 190-270 Celsius degrees. The results showed, that temperature had significant impact to CO2 conversion, methanol yield and selectivity. ZnO/CuO/SBA-15/kaolin catalyst showed the highest activity at 250 degrees, with the space-time yield of methanol generation reaching 50 mg h-1gcat-1.
