CATALYST FOR PREPARING VINYL CHLORIDE BY CRACKING 1,2-DICHLOROETHANE, AND PREPARATION METHOD, USE, AND REGENERATION METHOD

Document Type and Number:

WIPO Patent Application WO/2021/114175

Kind Code:

A1

Abstract:

The present application discloses a catalyst for preparing vinyl chloride by cracking 1,2-dichloroethane, and a preparation method, use, and a regeneration method. The catalyst for preparing vinyl chloride by cracking 1,2-dichloroethane comprises a silica-alumina molecular sieve. The catalyst for preparing vinyl chloride by cracking 1,2-dichloroethane has high reactivity and good selectivity, and said catalyst solves the problems in the prior art that the preparation of vinyl chloride by cracking 1,2-dichloroethane has a high reaction temperature and great energy consumption and is easy to coke and deposit carbon.
