Abstract

The invention relates to a permselective membrane (1) for removal of water from water-containing gas mixtures, said permselective membrane (1) being a carbon membrane of a material whose structure is graphite similar and formed by at least one sequence of layers of the material, the layers being arranged in planes, adjacent layers having an average distance between the layers of less than 0.45 nm (4.5 Å), and the sequence of layers being turbostratically disordered. The invention further relates to processes for preparing membrane (1) and to uses of membrane (1) for exchanging water between two gas streams and also for removing water from chemical equilibrium reactions. Assemblies comprising membrane (1) on porous ceramic carriers (2) and apparatuses for separating water from a water-containing gas mixture are also described.
