摘要：

The effect of the Cu/Ni ratio on CO2 hydrogenation at 773 K and 873 K was studied by XRD, TPR, H-2 and CO2- TPD. There exists strong interaction between Cu and Ni components. At high temperature (773 K and 873 K), the products are CO, CH4 and H2O without CH3OH formation. The Cu/Ni ratio has a significant effect on the conversion and selectivity. Cu favors CO formation while Ni is of benefit in CH4 formation. (C) 1999 International Association for Hydrogen Energy. Published by Elsevier Science Ltd. All rights reserved.
