Abstract
A Fischer-Tropsch process for producing hydrocarbons from synthesis gas which originates e.g. from biomass gasification, using membrane separators. In the process, an input stream which comprises hydrogen, carbon monoxide as well as further gases and/or vapours is initially fed to a first membrane stage 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 of the first membrane stage comprising steam and carbon dioxide and a retentate stream of the first membrane stage containing hydrogen and carbon monoxide.
