Abstract

In this study, CuO/ZnO/Al2O3 (30:30:40) model catalysts were prepared (by 3 different methods) for the synthesis of methanol from H2/CO2 (75:25) mixture in a fixed-bed flow reactor. XRD and Rietveld analyses showed that all samples had the same crystalline structure and crystalline phase composition. However, the catalytic performance of these samples is very different in both the product selectivity and the CO2 conversion to methanol. Then, a special attention was focused on the catalyst morphology in regard to the pore size distribution and SEM images. It is noted that the interaction between CuO-ZnO and alumina plays an important role in the catalytic activity. The study also showed that minor differences in preparation parameters can lead to remarkable differences in the catalyst performance.
