CO2-FACILITATED TRANSPORT MEMBRANE, AND METHOD FOR MANUFACTURING SAME

摘要

[Problem] To stably provide a CO2-facilitated transport membrane that can be applied to a CO2 permeable membrane reactor and that has excellent carbon dioxide permeability and CO2/H2 selectivity. [Solution] Provided is a CO2-facilitated transport membrane in which a gel layer (1) composed of a hydrogel film is carried on a hydrophilic porous membrane (2). More preferably, the gel layer (1) carried on the hydrophilic porous member (2) is covered and supported by hydrophobic porous membranes (3, 4). The gel film includes a deprotonating agent including an alkali metal element together with glycerin. The deprotonating agent is preferably a carbonate or a hydroxide of an alkali metal element, and more preferably, the alkali metal element is potassium, cesium, or rubidium.
