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.

Method and apparatus for producing synthetic fuels

When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.

Process and plant for producing hydrocarbons

In a method for the production of propylene, a charge stream containing Cto Colefins is evaporated, superheated, mixed with hot water vapor, the olefins vapor mixture converted on a zeolite catalyst, the reaction mixture formed thereby cooled, and then partially condensed. In order to increase the yield of propylene, the gaseous phase containing ethylene, propylene, Cto Colefins, and additional hydrocarbons that is accumulated during the partial condensation is compressed, the gaseous and liquid phase containing propylene, ethylene, and other light hydrocarbons that exit from the compression step is separated into a gaseous phase containing propylene, ethylene, and other light hydrocarbons and a liquid phase containing C+ olefins, and the liquid phase is separated into a fraction containing Cto Colefins and a fraction containing C+ olefins.
