Title
(EN) METHOD FOR PRODUCING SEPARATION MEMBRANE
(FR) PROCÉDÉ DE PRODUCTION D'UNE MEMBRANE DE SÉPARATION
(JA) 分離膜の製造方法
Abstract
(EN)
A method for producing a separation membrane where a zeolite film is formed on an inorganic oxide porous supporting body, said method comprising: a surface layer formation step wherein a surface layer containing 90% by weight or more of silica is formed on at least one of the surface of the supporting body and the inside of the supporting body in the vicinity of the surface of the supporting body; a loading step wherein the surface and/or the inside of the surface layer is loaded with a seed crystal of zeolite and a component that contains a structure directing agent; and a steam treatment step wherein the member obtained in the loading step is subjected to a treatment in a heated steam atmosphere.
(FR)
L'invention concerne un procédé de production d'une membrane de séparation où un film de zéolite est formé sur un corps de support poreux d'oxyde inorganique, ledit procédé comprenant : une étape de formation de couche de surface dans laquelle une couche de surface contenant 90 % en poids ou plus de silice est formée sur la surface du corps de support et/ou l'intérieur du corps de support au voisinage de la surface du corps de support ; une étape de chargement dans laquelle la surface et/ou l'intérieur de la couche de surface sont chargés avec un germe cristallin de zéolite et un composant qui contient un agent directeur de structure ; et une étape de traitement à la vapeur dans laquelle l'élément obtenu dans l'étape de chargement est soumis à un traitement dans une atmosphère de vapeur chauffée.
(JA)
無機酸化物多孔質支持体上にゼオライト膜が形成された分離膜の製造方法であって、前記支持体の表面、および前記支持体の表面付近の前記支持体の内部、の少なくとも一方に、シリカを90重量%以上含む表面層を形成する表面層形成工程と、ゼオライトの種結晶及び構造規定剤を含有する成分を、前記表面層の表面、内部またはその両方に担持する担持工程と、前記担持工程で得られた部材を、加熱水蒸気雰囲気で処理する水蒸気処理工程と、を含む、分離膜の製造方法。
