摘要

The ZSM-5 type membrape was prepared on a flat cordierite support by low temperature chemical vapor deposition (LTCVD) of a silica layer,followed by an in situ trystallization in vapor phase.The membrane obtained consisted of loosely-packed zeolite crystals in the pores of the support.The silica-alumina ratio of the membrane zeolite layer determined by EDX was low,indicating a hydrophilic nature of the membrane.The performances of the ZSM-5 membrane in the separation of water-alcohol mixtures by pervaporation were studied and discussed with respect to the membrane structure and the alcohol nature.The membrane showed very high selectivity towards water in the water-ethanol mixture.The transport mechanism of the membrane has also been discussed.
