Zusammenfassung:The invention concerns a process for converting methanol or dimethyl ether to olefins in the presence of a dealuminated mordenite, wherein the reactant (methanol or dimetyl ether) is diluted with a gas or with steam. It is characterised in that the obtained olefins are fractionated so as to recycle at least a part of the olefins having at least 4 carbon atoms per molecule. The invention is particularly applicable to the production of propylene.
