Methanol-to-propylene process: Perspective of the most important catalysts and their behavior

The methanol-to-propylene (MTP) process is a route of methanol conversion to hydrocarbons, which is in high demand because of limited oil resources. The present paper discusses the effect of catalyst structure on the MTP process conditions, and the role of different zeolite factors, such as acidity, crystal size, mesoporosity, and topology, on the activity and selectivity of the MTP reaction.

Graphical AbstractVarious acidic catalysts, mostly zeolites, have been evaluated for methanol conversion to propyele. Zeolites-microporous crystalline aluminosilicates and their ZSM-5 forms are widely used in methanol-to-propylene (MTP) process because of their strong acid sites within uniform micropores as size and shape selective catalysts.Figure optionsDownload full-size imageDownload as PowerPoint slide
