Abstract

CO 2 -facilitated transport membrane that can be applied to a CO 2 -permeable membrane reactor is stably provided. The CO 2 -facilitated transport membrane is provided such that a gel layer (1) composed of a hydrogel membrane is deposited onto a porous membrane (2). More preferably, the gel layer (1) deposited onto a hydrophilic porous membrane (2) is coated with and supported by hydrophobic porous membranes (3) and (4). The gel layer contains a deprotonating agent including an alkali metal element together with glycine. 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.

Description

technical field [0001] The present invention relates to CO used in the separation of carbon dioxide 2 Facilitated transport membrane and its production method, especially CO capable of separating carbon dioxide contained in reformed gas for fuel cells and the like mainly composed of hydrogen with high selectivity to hydrogen 2 Facilitated transport membrane, and CO capable of separating carbon dioxide contained in exhaust gas with high selectivity for nitrogen 2 Facilitates the transport of films. Background technique [0002] Conventionally, methods for selectively separating carbon dioxide have been studied in various ways because of their wide range of applications. For example, the purity of hydrogen can be improved by selectively separating carbon dioxide from reformed gas for fuel cells and the like. In addition, it is expected that the progress of global warming can be slowed down by selectively separating and storing carbon dioxide, which is one of the causes of g...
