The invention relates to a permselective membrane () for removal of water from water-containing gas mixtures, said permselective membrane () 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 &#x212b;), and the sequence of layers being turbostratically disordered. The invention further relates to processes for preparing membrane () and to uses of membrane () for exchanging water between two gas streams and also for removing water from chemical equilibrium reactions. Assemblies comprising membrane () on porous ceramic carriers () and apparatuses for separating water from a water-containing gas mixture are also described.

Carbon membrane, process for the manufacture of carbon membranes and use thereof

The use of solutions of ethylenically unsaturated polyesters for production of carbon membranes suitable for gas separation, and a process for producing carbon membranes suitable for gas separation, comprising the steps of a) coating a porous substrate with a solution of ethylenically unsaturated polyester, b) drying the polyester coating on the porous substrate by removing the solvent, and c) pyrolyzing the polyester coating on the porous substrate to form the carbon membrane suitable for gas separation, it being possible to conduct any of steps a) to c) or the sequence of steps a) to c) more than once.
