| Outline of Final Research Achievements |
In this study, we prepared zeolite membranes such as MFI(ZSM-5), MOR, RHO and AEI using F-containing gels by a single hydrothermal synthesis. The role and location of F ion were also clarified. The membrane prepared from F-containing gel had a high flux and a high separation factor for a gas separation of CO2/CH4 or for a water/ethanol mixture. Especially the membranes showed good acidic durability and dehydration performance. The membrane prepared from the fluoride-containing precursor gel had a better acid stability and reproducibility than the membrane prepared from non fluoride-containing precursor gel. Long-term acid-stable zeolite membranes for the dehydration process will certainly advance the acceptance of zeolite membranes in industrial processes.
