Zusammenfassung:The present invention relates to a process for the production of olefins from oxygenates, comprising the following steps: (i) heterogeneously catalyzed conversion of methanol to a product stream containing a C3− and a C4+ fraction, (ii) distillation of the product stream for separating the C3− fraction from a bottom product, and (iii) distillation of the bottom product for separating a stream containing the C4+ fraction and dimethyl ether from a stream containing water and methanol. Furthermore, the invention also comprises a plant for carrying out this process.
