在α-Al 2 O3多孔支撑管上制备了STT型纯硅沸石（Si-STT）膜，并研究了其气体渗透性能。Si-STT膜的H2渗透率在高温下增加。由于Si-STT膜具有最佳的孔径，不会阻碍氢气的渗透，因此在H2/甲苯分离试验中实现了高渗透性和H2选择性。
STT-type pure silica zeolite (Si-STT) membrane is prepared on an α–alumina porous support tube and the gas permeation properties of the Si-STT membrane are investigated. The H2permeance of the Si-STT membrane increases at high temperatures. A high permeance and H2selectivity are achieved for the H2/toluene separation tests because the Si-STT membrane has an optimal pore size that does not block the permeation of hydrogen.
