Fundamental study on membrane separation using unique separation properties of microporous thin films

我们对利用结晶微孔材料开发无机膜进行了基础性研究。我们研究的最终目标是通过创造新的膜材料，为未来能源和化学过程的进一步绿色做出贡献。在本研究中，我们的目标是详细阐明膜的形成途径和机制，提取透选择性的影响因素，阐明水和有机物混合物的渗透和分离机制，以实现膜分离。对于y型沸石膜，我们阐明了其成膜机理，并成功研制出了高效脱水水/异丙醇混合物的膜。本研究制备的硅石-1膜具有优异的分子筛分性能。成功地确定了硅石-1膜的渗透分离行为。除了沸石膜外，我们还研究了利用结晶微孔磷酸铝酸盐制备新型膜，并开发了一种对水/乙酸蒸汽混合物具有高分离性能的膜。

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.
