Olefin metathesis mixed catalysts and method for producing cis-reactions and propylene production method using the same

摘要

Polymerization reaction and a side reaction, a highly selective reaction does not occur between the isomerization and 1-butene and other molecules from 2-butene to 1-butene, and a highly active olefin metathesis reaction mixture catalyst I will provide a. Providing a metathesis catalyst tungsten oxide supported on a silica carrier, the olefin metathesis reaction mixture catalyst comprising a cocatalyst which is complexed by an oxide of at least three metallic elements of the groups 1 and 2 of the metal element , by using the olefin metathesis reaction to produce propylene from ethylene and 2-butene, it is possible to increase the solid basic so as to facilitate metathesis reactions, isomers of 2-butene contained in the raw material gas suppressing the influence of a gas containing, it can increase the propylene production efficiency even at a low temperature.
