Chapter 10 Sulfidation of Hydrogenation Catalysts and Restoration of Their Activity 1. Catalyst sulfidation 2. Catalyst regeneration 3. Catalyst hydrogen activation
The catalyst is initially in an oxidized state and reacts with a sulfidation agent to be reduced to a sulfided state. After being used for a period of time, the catalyst becomes coked and loses its activity; regeneration can be carried out either outside the reactor or inside it
Vulcanization is divided into dry vulcanization and wet vulcanization
