摘要：Zeolite ZSM  5 membrane,  whose permeance was up to 10    -6   mol/(m  2·s·Pa) and a magnitude higher than that of other groups,  was prepared on   α    Al  2O  3 support 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,  SEM and single gas permeances measurements,  which showed that it was dense and integral without large intercrystal pores and cracks. The permeance of H  2,
