METHOD FOR GENERATING HYDROCARBONS, IN PARTICULAR GASOLINE, FROM SYNTHESIS GAS

摘要

The invention relates to a method for generating gasoline hydrocarbons by means of converting synthesis gas into a compound comprising oxygen, such as methanol and/or dimethyl ether, in a first converter and further converting said gas into hydrocarbons in a second converter. The method is especially characterized by the fact that synthesis gas that is not converted in the first converter is recycled, and light hydrocarbons and non-reacted components of the synthesis gas are recycled from the product flow of the second converter into the first or second converter. The return flow of said components allows partial pressures to be adjusted, in particular that of methanol in the second converter, wherein product quality is improved. In order to further improve product quality, the process is preferably run under isothermal conditions and conditions of incomplete conversion.
