摘要： The present application discloses a catalyst for pyrolysis of 1,2-dichloroethane (1,2-DCE) to prepare vinyl chloride monomer (VCM), a preparation method, a use, and a regeneration method thereof. The catalyst for pyrolysis of 1,2-DCE to prepare VCM includes a silicon-aluminum molecular sieve. The catalyst for pyrolysis of 1,2-DCE to prepare VCM has high reaction activity and excellent selectivity and solves the problem that the pyrolysis of 1,2-DCE to prepare VCM in the prior art involves high reaction temperature and large energy consumption and is prone to coking and carbon deposition.
