Preparation of Al_2O_3-Supported Ni Catalyst and its Catalytic Hydrogenation Performance

摘要

The Al_2O_3-Supported Ni Catalyst was prepared by chemical reduction method, and take benzaldehyde as catalytic hydrogenation model to explore the effect in catalytic hydrogenation of benzaldehyde at different time and temperatures. The results show that the best temperature is between 60°C and 80°C, and the catalytic time is about 1-2 h. Furthermore, the catalytic effect of Ni-Co/Al_2O_3 is best, it should be due to Co and Ni forming to alloys and obtain the function of the dual catalyst, which is conducive to benzaldehyde was activated and forming benzyl alcohol.
