  • Patent number: 9962648
    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 ?), 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.

  • Patent number: 9611187
    Abstract: The invention relates to a method of carrying out a chemical equilibrium reaction using a permselective membrane, wherein quantitative proportions of at least one product obtained in the reaction are separated and removed from the reaction through the action of the permselective membrane. The chemical equilibrium reaction is carried out in the presence of a water-containing gas mixture, and a permselective membrane made from a material having a porous structure with mean pore sizes of less than 0.45 nm (4.5 ?), which material is hydrophobic at least on the free surfaces thereof is used.
