Catalyst for propylene production, method for producing same, and method for producing propylene

摘要

Disclosed is a catalyst for propylene production, which is used for the purpose of producing propylene from one or more materials selected from the group consisting of methanol, dimethyl ether and olefins having 4-8 carbon atoms. The catalyst for propylene production is characterized in that: the catalyst is composed of a binder-less crystalline aluminosilicate molded body having a silicon/aluminum atomic ratio of 500-10,000; and the crystalline aluminosilicate contains an MFI crystal structure and/or an MEL crystal structure. With the use of this catalyst for propylene production, production amounts of aromatic components and paraffin components such as ethylene and propane are reduced, while achieving excellent propylene yield, propylene/propane ratio and catalyst life.
