Description

technical field

[0001] The invention relates to a catalyst for producing propylene from methanol, a preparation method and application. Background technique

[0002] Propylene is the basic organic raw material in the modern chemical industry, and its demand will increase. The traditional route to produce propylene is through cracking of naphtha. The disadvantage of this route is that it is overly dependent on petroleum. The production of low-carbon olefins from methanol uses non-petroleum resources, that is, coal or natural gas as raw materials to produce organic raw materials such as ethylene and propylene through methanol, including MTO technology with ethylene and propylene as the main product and MTP with propylene as the main product. Technology, which breaks through the limitation of oil resources. This technology was originally discovered by the Mobil Company of the United States when studying the methanol-to-gasoline (MTG) catalytic process. By changing the process...
