摘要：

The effect of vanadium addition to Cu/gamma-Al2O3 catalyst used in the hydrogenation of CO2 to produce methanol was studied. It was found that the catalytic performance of the Cu-based catalyst improved after V addition. The influence of reaction temperature, space velocity and the molar ratio of H-2 to CO2 on the performance of 12%Cu-6%V/gamma-Al2O3 catalyst were also studied. The results indicated that the best conditions for reaction were as follows: 240 degrees C 3600 h(-1) and a molar ratio of H-2 to CO2 of 3:1. The results of XRD and TPR characterization demonstrated that the addition of V enhanced the dispersion of the supported CuO species, which resulted in the enhanced catalytic performance of CU-V/gamma-Al2O3 binary catalyst.
