Abstract: Zeolite ZSM-5 membrane, whose permeance was up to10-6mol/(m2·s·Pa) and a magnitude higher than that of other groups, was prepared on α Al2O3support by multi in situ hydrothermal treatments, using optimized sol prescription and cheap n butane as the structure directing agent.The membrane was characterized by means of XRD, SEMand single gas permeances measurements, which showed that it was dense and integral without large intercrystal pores and cracks.The permeance of H2, N2, C3H8 and n C4H10was up to2.35×10-6, 1.0×10-6, 1.13×10-7and4.9×10-8mol/(m2·s·Pa), respectively.Ideal selectivity of H2/N2, H2/C3H8and H2/ n C4H10was2.45, 20.8 and48, respectively

Key words: Hydrothermal crytallization, Zeolite ZSM-5 membrane, Permeance, Selectivity
