Abstract

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 C1-C4 hydrocarbons and a stream rich in C5+ hydrocarbons. The stream rich in C5+ hydrocarbons is divided into a stream rich in C5 and C6 hydrocarbons and a stream rich in C7+ hydrocarbons, wherein the stream rich in C5 and C6 hydrocarbons is at least partly subjected to an etherification with methanol. The ethers thus obtained are admixed to the gasoline product stream.
