Abstract

The application relates to a process for the preparation of olefins by reaction of methanol and/or dimethyl ether in the presence of zeolite catalysts at elevated temperature, in which, as catalysts, borosilicate zeolites are used which are shaped with binder mixtures of silica and alumina whose aluminium content is </= 10 % by weight. The advantage lies in an improved yield of C2-C4-olefins at the expense of the formation of higher hydrocarbons and the formation of undesired by-products such as methane.
