【 摘 要 】

References(12)MFI zeolite membranes were prepared by a secondary growth method on symmetric tubular supports. Adding fluoride ions to the synthesis gel significantly shortened the hydrothermal synthesis time. In addition, membranes prepared with fluoride ions showed more than ten-times higher hydrogen permeation rate than membranes prepared from conventional gel. MFI zeolite membrane showed hydrogen selectivity in hydrogen/toluene separation.
