Title:
GAS SEPARATION MEMBRANE
Document Type and Number:
Japanese Patent JP2018167150
Kind Code:
A
Abstract:
To acquire a gas separation membrane that has high permeability and selectivity worth of being put into practical use by controlling a grain boundary of an inorganic film.SOLUTION: In a module (110) internally provided with an inorganic composite membrane (106) having a gas separation active layer, a grain boundary film (303) is formed by forming an inorganic layer or filling an organic material at a grain boundary (203) of an inorganic film using pressure difference between an inside and an outside of a composite membrane (106), thereby filling in the grain boundary.SELECTED DRAWING: Figure 1
