Carbon dioxide adsorption apparatus and adsorption element and method for manufacture thereof

摘要

A carbon dioxide adsorption element rapidly adsorbs a large amount of carbon dioxide, and regenerates amine groups for carbon dioxide adsorption rapidly and uniformly with high-temperature air. The carbon dioxide adsorption element 110 for adsorbing carbon dioxide in air comprises a foil-like or plate-like support member 111 , a porous aluminum oxide film 112 covering the support member 111 , and the amine groups 113 clinging to the inner surface of each pore 112 a of the film 112 for carbon dioxide adsorption. The film 112 is formed by oxidation of aluminum or aluminum alloy. The depth direction of each pore 112 a of the film is the thickness direction of the support member 111.
