CATALYST FOR PROPYLENE PRODUCTION, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING PROPYLENE

摘要

Disclosed is a propylene production catalyst for producing propylene from one or more selected from a group consisting of methanol, dimethyl ether and olefins having from 4 to 8 carbon atoms. The catalyst comprises a binderless crystalline aluminosilicate shaped body having a silicon/aluminium atomic ratio of from 500 to 10000, in which the crystalline aluminosilicate contains an MFI-type crystal structure and/or an MEL-type crystal structure. The catalyst reduces the production amount of ethylene, paraffin components such as propane, and aromatic components, and increases the propylene yield and the propylene/propane ratio, and the catalyst life is long.
