Abstract:
1. A process for producing hydrocarbons from biomass in which an input stream ( 1 ) from biomass gasification or from another synthesis gas production process which comprises hydrogen, carbon monoxide as well as further gases and/or vapours is initially fed to a first membrane stage (GP 1 ) which comprises a steam-selective and carbon dioxide-selective membrane and through which at least some of the steam present in the input stream and some of the carbon dioxide present in the input stream are separated from the input stream to form a permeate stream ( 3 ) of the first membrane stage comprising steam and carbon dioxide and a retentate stream ( 2 ) of the first membrane stage containing hydrogen and carbon monoxide, the retentate stream ( the product stream ( the permeate stream ( the retentate stream ( the gas phase ( the permeate stream ( the permeate stream (
