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.

Regeneration method and application of nitrogen-containing carbon catalyst

A catalyst for preparing chloroethylene by cracking 1,2-dichloroethane and a preparation and regeneration method thereof are disclosed in the present application. A catalyst for preparing chloroethylene by cracking 1,2-dichloroethane includes a carrier and a nitrogen-containing carbon as an active component of the catalyst with the nitrogen-containing carbon being loaded on the carrier. The method for preparing the catalyst includes: supporting an organic matter on an inorganic porous carrier and then performing a carbonization-nitridation process by pyrolysis in an atmosphere containing the nitrogen-containing compound. The method for regenerating the catalyst includes: calcinating the catalyst with deactivated carbon deposit in an oxidizing atmosphere to remove all the carbonaceous portions on the surface, and repeating the above preparation process of the catalyst. The catalyst reduces reaction temperature, reduces energy consumption, reduces production cost, and improves selectivity and conversion rate and is inexpensive and reproducible, and has a long service life.

Catalyst for preparing chloroethylene by cracking 1,2-dichloroethane and a preparation and regeneration method thereof

A method for preparing a supported carbon catalyst, the method includes at least the following steps: contacting a gas containing an organic silicon source with a silicon oxide-based material to obtain a precursor; contacting the precursor with a gas containing an organic carbon source to obtain the supported carbon catalyst. The temperature and energy consumption of the chemical vapor deposition of heteroatom-containing carbon material on silica-based materials can be greatly reduced in this method, and the cost of the catalyst can be effectively reduced.
