| 摘要 |
The catalytic mixture resulting of a metal powder catalyst with a solid material (referred to here as a reaction-aid) that has good filtering properties, does not interfere with the reaction, does not interfere with recycling the catalyst back into the reaction, does not interfere with the refining and recovery of the metal from the catalyst after it is spent, and will not become separated from the catalyst during the preparation of this catalytic mixture, the chemical reaction or the separation of this catalytic mixture from the reaction medium, whereas the ratio of the reaction aid to the catalyst ranges from 0.05 to 20 on a weight basis. A preferred metal powder catalyst is acetylene black supported precious metal. Preferred reaction aids are sibunit powder or activated carbon. The catalytic mixture can be used for the catalytic transformation of compounds, such as the hydrogenation of olefins, or the hydrogenation of nitro compounds. |
