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 in which: a zeolite film is formed on an inorganic oxide porous substrate; and the main component of a zeolite formation part of the substrate is amorphous SiO2. This method for producing a separation membrane comprises: a first step wherein a seed crystal of zeolite and an alkali component containing a structure-directing agent are formed on the surface of the substrate; and a second step wherein a formed body obtained in the first step is processed in a heated water vapor atmosphere. Consequently, a zeolite film is formed on the substrate surface in this method for producing a separation membrane.
(FR)
L'invention concerne un procédé de production d'une membrane de séparation dans lequel: un film de zéolite est formé sur un substrat poreux d'oxyde inorganique; et le composant principal d'une partie de formation de zéolite du substrat est du SiO2 amorphe. Ce procédé de production d'une membrane de séparation comprend: une première étape dans laquelle un germe cristallin de zéolite et un composant alcalin contenant un agent directeur de structure sont formés sur la surface du substrat; et une seconde étape dans laquelle un corps formé obtenu dans la première étape est traité dans une atmosphère de vapeur d'eau chauffée. Par conséquent, un film de zéolite est formé sur la surface du substrat dans ce procédé pour produire une membrane de séparation.
