NaA zeolite membranes have been found a potential application in the separation of the small-sized gas molecules by molecular sieving and dehydration of liquid mixtures by pervaporation. However, there are some problems in the preparation in the NaA zeolite membranes such as the scarce support types, insufficient study on the synthesis rules and few literature concerning the NaA zeolite membranes preparation on the inner surface of the tubular support.
