摘要

Porous SAPO-34 molecular sieve membranes supported on α-Al₂O₃ substrates have been successfully prepared by in-situ synthesis. It is found that several synthesis times are needed and the placement of the substrate in the autoclave is important to prepare a defect-free SAPO-34 membrane. The best ideal selectivity of H₂/N₂ and CO₂/N₂ of the membranes is 11.17 and 7.09 respectively. N-butane has a permeability of zero, indicating that the membranes are defect-free and the permeability mechanism through the membranes is molecular sieving.
