Abstract

The invention disclose a method for preparing rare earth type hydrochlorination catalyst of acetylene comprising tin, which belongs to the field of preparing the hydrochlorination catalyst of acetylene. The catalyst comprises stannic chloride, rare earth chloride, other metal chlorides and carriers, wherein the rare earth chloride is adopted as cerium chloride or lanthanum chloride, and the carriers are cerium-zirconium powder or zirconia. The catalyst is prepared by soaking method, can be applied to fixed-bed reactors, has low cost, has no pollution, and has good catalytic activity and high selection in the process of producing vinyl chloride by hydrochlorination of acetylene.

Description

Technical field

[0001] The invention relates to a preparation method of an acetylene hydrochlorination catalyst, in particular to a preparation method of a tin-containing rare earth acetylene hydrochlorination catalyst. Background technique

[0002] Vinyl chloride (VCM) is a monomer for the synthesis of polyvinyl chloride (PVC). Almost all vinyl chloride (98%) in the world is used to produce polyvinyl chloride. Polyvinyl chloride is one of the five general synthetic resins. It has good physical and mechanical properties. It is used in the production of building materials, packaging materials, electronic materials and daily consumer goods. It is widely used in industry, agriculture, transportation, packaging and other fields. China's plastics industry has formed a relatively complete industrial system and has become a basic material industry that goes hand in hand with steel, cement, and wood. As a new type of material, its application fields have far surpassed the above three mat...
