| Abstract: | Raney-Ni catalyst immobilized with both strong and weak magnetic materials is success-fully applied in the homemade and bubble fixed-bed reactor. The activity and stability of the cata-lyst are improved a lot for hydrogenation of both 5-(p-hydroxyl)-benzylhydantoin and or-nitro-ethyl benzene. The results show that the conversion rates of 5-(p-hydroxyl)-benzylhydantoin and or-nitro-ethyl benzene are over 90% and 99%, respectively. There is hardly any change for activity of the catalyst after 300 h operation. |
