Title:
REGENERATION METHOD AND APPLICATION OF NITROGEN-CONTAINING CARBON CATALYST
Document Type and Number:
WIPO Patent Application WO/2021/139429
Kind Code:
A1
Abstract:
Disclosed is a method for regenerating a nitrogen-containing carbon catalyst. The nitrogen-containing carbon catalys is baked in a nitrogen-containing atmosphere to form the regenerated nitrogen-containing carbon catalyst. The method is a universal method suitable for a nitrogen-doped, carbon-type catalyst. The method can be used to regenerate a nitrogen-containing carbon catalyst for cracking 1,2-dichloroethane to produce vinyl chloride. The method can greatly reduce the production cost of the catalyst, and increase the service life of the catalyst, and the regeneration process is fast and has lower temperature requirements, thus the method is easy to control.
