Abstract:NaA zeolite membrane was synthesized with high permeance on porous alumina substrate by the vapor phase transformation method. The membranes were characterized by XRD and SEM techniques. The XRD results showed that the membranes after the synthesis time of 24 h consisted of the pure NaA zeolite crystals. The SEM results showed that the membranes after the synthesis time of 48 h consisted of intergrown zeolite crystals. The H2 permeance of the NaA zeolite membranes was higher than 2.0 × 10?6 mol/(Pa · m2 · s), and the maximum of the gas H2/C3H8 permselectivity was 7.15, which is higher than the corresponding Knudsen diffusion selectivity of which is 4.69.
Keywords:NaA zeoltie membrane  vapor phase transformation  synthesis  separation
