Abstract

A process for producing propylene from methanol, wherein methanol vapor is reacted on a first catalyst to obtain a first vapor mixture containing dimethyl ether (DME), which is reacted on a form-selective zeolite catalyst disposed as bed in at least two series-connected shaft reactors to produce a product mixture containing propylene.
