Publication number: 20090050531Abstract: Disclosed is a method for the production of synthetic fuels, wherein, in a first step, a gas mixture consisting of methanol and/or dimethyl ether and/or another oxygenate and water vapor is reacted at temperatures of 300-600° C. in order to form olefins with, preferably, 268 carbon atoms. In a second step, the olefin mixture thus obtained is oligomerized at an elevated pressure to form higher olefins with predominantly more than 5, preferably 10-20 carbon atoms. According to said method, a) the production of olefins in the first step is carried out in the presence of a gas flow which essentially consists of saturated hydrocarbons which are separated from the product flow of the second step and returned to the first step, and (b) the production of olefins is carried out in the second step in the presence of a flow of water vapor which is separated from the product flow of the first step and returned to the first step.Type: ApplicationFiled: December 1, 2005Publication date: February 26, 2009Inventors: Martin Rothamel, Bernd Ahlers, Matthias Wagner, Harald Kompel, Jurgen Hofmockel
