N2  - Catalytic hydrogenation of CO2 into fuels and chemicals is regarded as one of the most promising alternatives to reduce the concentration of CO2 in the atmosphere. In this study, double-promoted Cu/ZnO catalysts were prepared on Al2O3 and CNTs supports via impregnation method. The physicochemical properties of the catalysts were characterized by XPS, TEM, N2 adsorption, H2-TPR and CO2-TPD analyses. Introduction of Nb and Zr promoters into the Cu-based catalysts on CNTs support resulted in smaller Cu nanoparticles and improved reducibility compared to those of the Al2O3-supported catalyst. The catalyst activity was evaluated in a fixed-bed stainless steel reactor operated at 22.5 bar and 523K. Conversion of CO2 higher than 20 was achieved and product distribution was influenced by the type of catalyst supports. © 2019 Trans Tech Publications, Switzerland
