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.
