In producing C-Colefins, in particular propylene, from an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, the educt mixture is reacted in a reactor on a catalyst to a reaction mixture comprising low-molecular olefins and gasoline hydrocarbons, which in a first separating device is separated into a mixture rich in Colefins, a mixture rich in Cgasoline hydrocarbons, and an aqueous phase. To increase the yield of propylene the mixture rich in Cgasoline hydrocarbons is supplied to a second separating device, in which the aromatics contained in the mixture are separated. The residual stream largely free from aromatics is at least partly recirculated to the reactor.

For producing synthetic fuels, an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, is converted to olefins on a catalyst in a first process stage, and this olefin mixture then is divided in a separating means into a stream rich in C-Chydrocarbons and a stream rich in Chydrocarbons. The stream rich in Chydrocarbons is divided into a stream rich in Cand Chydrocarbons and a stream rich in Chydrocarbons, wherein the stream rich in Cand Chydrocarbons is at least partly subjected to an etherification with methanol. The ethers thus obtained are admixed to the gasoline product stream.
