Hydrogen-butane separation through MFI-type zeolite membrane grown by a secondary growth method, which is a method of growing up seed crystals secondarily and obtaining a compact membrane, was studied. In the permeation tests of the binary gas mixtures of H2/iso-C4 and H2/n- C4, both iso- and n- C4 permeation was decreased by the adsorption of water in the membrane, resulting in very high separation factors exceeding 103 at 323 K. After the removal of adsorbed water, the membrane was H2 selective in the H2/iso-C4 mixture and n-C4 selective in the H2/n- C4 mixture.
