Title:
オレフィンメタセシス反応用混合触媒およびその製造方法並びにそれを用いたプロピレン製造方法
Document Type and Number:
Japanese Patent JP5959658
Kind Code:
B2
Abstract:
Provided is mixed catalysts for an olefin metathesis reaction having a high selectivity so that side reactions do not take place and having a high activity, which side reactions are polymerization reactions, isomerization from 2-butene to 1-butene, and reactions of 1-butene with other molecules. Mixed catalysts for an olefin metathesis reaction can be provided, the mixed catalyst comprising a metathesis catalyst which is tungsten oxide supported on a silica carrier and a co-catalyst that is composited from at least three oxides of Groups 1 and 2 metallic elements. By using the catalyst an olefin metathesis reaction of generating propylene from ethylene and 2-butene, the solid basicity to promote the metathesis reaction can be increase, and influences of gas containing isomers of 2-butene contained in raw material gas can be inhibited to increase the production efficiency of propylene even at low temperatures.
