A defect-free SAPO-44 zeolite membrane firmly anchored the porous α-Al₂O₃ plate substrate was successfully synthesized. The separating results showed that the H₂/N₂ and H₂/CO permselectivities were higher than those of the corresponding Knudsen diffusion and the substrate,attaining 5.78 and 7.15 respectively.
- SAPO-44,
- zeolite membrane,
