Title:
有機アルカリで修飾された複合触媒及び一酸化炭素の水素化によるエチレンの製造方法
Document Type and Number:
Japanese Patent JP7007763
Kind Code:
B2
Abstract:
An organic base modified composite catalyst and a method for preparing ethylene by means of hydrogenation by carbon monoxide. Mixed gas of carbon monoxide and hydrogen is used as a reaction raw material to carry out a conversion reaction on a fixed bed or a moving bed. The catalyst is a composite catalyst prepared by combining component I and component II together in a mechanical mixing manner; The active ingredient of component I is a metal oxide, and component II is a molecular sieve with an organic base modified MOR structure; and the organic base is aliphatic amine. The reaction process has high product yield and selectivity; the C2-C3 olefin selectivity is as high as 78-87%, wherein the selectivity of hydrocarbon products containing four or more C atoms is less than 10%; the selectivity of byproduct methane is extremely low (<9%), and the selectivity of ethylene reaches 75-82%.
