Abstract
A regeneration method of a nitrogen-containing carbon catalyst includes the following steps: roasting the nitrogen-containing carbon catalyst in a nitrogen-containing atmosphere to obtain a regenerated nitrogen-containing carbon catalyst. The method is a universal method, which is suitable for nitrogen-doped carbon catalysts and can be used to regenerate a nitrogen-containing carbon catalyst for producing vinyl chloride (VC) through 1,2-dichloroethane cracking. The method can greatly reduce the production cost of the catalyst and increase the service life of the catalyst, and a regeneration process thereof is fast, simple, and controllable, and does not require high temperatures.
