摘要：

Physical mixtures of Cu/SiO2 and ZnO/SiO2 catalysts have been studied for the synthesis of methanol from CO/CO2/H-2 at 250 degrees C and 10 bar pressure. It is found that the activities are very much higher for the physical mixtures than would be expected from the activities of either of these two catalysts in isolation. The results suggest that the high activity of conventional Cu/ZnO/Al2O3 catalysts may arise from a synergy between the Cu and ZnO phases.
