PROCESS FOR PRODUCING ZEOLITE SEPARATION MEMBRANE |
摘要 |
<p>The present invention provides a process for production of a zeolite separation membrane having a porous support composed mainly of alumina and a zeolite layer formed on the surface of, and inside the pores of, the porous support, the process comprising: a seed crystal-attaching step in which USY zeolite crystals are attached as seed crystals to the surface of, and inside the pores of, the porous support; a crude product-forming step in which: the porous support is contacted with a reaction solution containing silicon and aluminum, and the reaction solution is heated to form a crude product of the zeolite separation membrane; and a crude product-separating step in which the crude product of the zeolite separation membrane is separated from the reaction solution to afford the zeolite separation membrane. This process for production of a zeolite separation membrane makes it possible to produce an FAU zeolite separation membrane that can accomplish satisfactory separation of a mixture of organic solvent and water.</p> |
