Abstract/ Foreword

The alternative way to solve the greenhouse gas emission problems is carbon dioxide (CO2) capture and utilization. CO2 hydrogenation is one of the routes to obtain valuable chemicals and fuels such as methanol. The effect of indium (In) promoter on catalytic system Cu/Zn/SBA-15 has been studied. 1%In/Cu/ZnO/SBA15 and 6%In/Cu/ZnO/SBA15 catalysts have been synthesized by impregnation method and compared with Cu/Zn/SBA-15 catalyst (the content of Cu 30 wt.% and the content of Zn 1.4 wt.%). All catalysts have been characterized using XRD analysis, N2 adsorptiondesorption analysis, SEM-EDX and STEM analysis. CO2 hydrogenation was proceeded in a fixed-bed tubular micro-activity reactor at 20 bar 250 °C with H2 to CO2 molar ratio 4 to 1. The addition of In showed positive effect on the structural and textural properties of catalyst, but the activity in hydrogenation reaction showed opposite - the largest space-time yield of methanol was obtained with Cu/Zn/SBA-15 catalyst.
