摘要

MFI zeolite membranes were synthesized on porous α-alumina hollow fibers by in-situ hydrothermal synthesis. The membranes were further modified for H₂ separation by on-stream catalytic cracking deposition of methyldiethoxysilane (MDES) in the zeolitic pores. The separation performance of the modified membranes was characterized by separation of H₂/CO ₂ gas mixture at 500 C. Activation of MFI zeolite membranes by air at 500 C was found to promote catalytic cracking deposition of silane in the zeolitic pores effectively, which resulted in significant improvement of H ₂-separating performance. The H₂/CO₂ separation factor of 45.6 with H₂ permeance of 1.0 × 10^-8 mol m^-2 s^-1 Pa^-1 was obtained at 500 C for a modified hollow fiber MFI zeolite membrane. The as-made membranes showed good thermochemical stability for the separation of H₂/CO₂ gas mixture containing H₂O and H₂S, respectively. ©
