Synthesis and Characterization of Double-Promoted Copper-Based Catalysts for CO₂ Hydrogenation into Fuels

Abstract:

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.
