| Research Abstract |
We have carried out fundamental study for developing inorganic membranes using crystalline microporous materials. The final goal of our study is to contribute to make energy and chemical processes further green in future by creating novel membrane materials. In this study, our target was to clarify formation paths and mechanisms of membrane formation in detail, to extract gavering factors of permselectivity and to elucidate permeation and separation mechanisms for achieving membrane separation of mixtures containing water and orbganic substances. As for Y-type zeolite membrane, we elucidated its membrane formation mechanisms, and successfully developed membranes having high performance for dehydration of water/isopropyl alcohol mixtutes. Silicalite-1 membrane that we developed in this study showed excellent molecular sieving properties. Permeation and separation behavior through silicalite-1 membrane were successfully formulated. Apart from zeolite membrane, we have tackled to prepare a novel membrane using crystalline microporous aluminophospates, and developed a membrane showing high separation performance for water/acetic acid vapor mixture.
