Abstract
Disclosed is an absorbent for separation of carbon dioxide from mixed gases, comprising a mixture of i) a compound of the chemical formula 1 having one or more groups of three functional groups consisting of amino group attached to a tertiary carbon atom; carboxylate group; and hydroxyl group respectively, in a molecule, or a compound of the chemical formula 2 having one or more groups of two functional groups consisting of amino group attached to a quarternary carbon atom; and carboxylate group respectively in a molecule, and ii) an amine compound which promotes the reaction. The absorbent for separation of carbon dioxide of the present invention is advantageous economically, since its efficiency is excellent due to larger unit absorption amount of carbon dioxide, and the energy required for regeneration can be reduced due to the relatively wider difference of absorption amounts with temperature. In addition, it is advantageous for industrialization, since the solubility is excellent by using a compound presented as a form of carboxylic acid salts, and operation cost is low because there is no risk of evaporation due to high boiling point.
