Abstract :
MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with microwave technique. In this case the H2 permeance was obtained 2.8 × 10-6 mol/ (m2.s.Pa) with a H2/CO ideal selectivity of 4.9 at 373 K. The permeation results of four gas (H2, CO, N2, CH4) on the synthesized membrane were also investigated.
