ABSTRACT:
A process for producing a wide slate of fuel products from coal is provided by integrating a methanol-to-gasoline conversion process with coal liquefaction and coal gasification. The coal liquefaction comprises contacting the coal with a solvent under supercritical conditions whereby a dense-gas phase solvent extracts from the coal a hydrogen-rich extract which can be upgraded to produce a distillate stream. The remaining coal is gasified under oxidation conditions to produce a synthesis gas which is converted to methanol. The methanol is converted to gasoline by contact with a zeolite catalyst. Solvent for coal extraction is process derived from the upgraded distillate fraction or gasoline fraction of the methanol-to-gasoline conversion.
