Abstract
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 elementfor adsorbing carbon dioxide in air comprises a foil-like or plate-like support member, a porous aluminum oxide filmcovering the support member, and the amine groupsclinging to the inner surface of each poreof the filmfor carbon dioxide adsorption. The filmis formed by oxidation of aluminum or aluminum alloy. The depth direction of each poreof the film is the thickness direction of the support member
