Document Type and Number:
Japanese Patent JP7441557
Kind Code:
B2
Abstract:
A method for recovering carbon dioxide, said method comprising: a step (A1) wherein carbon dioxide is absorbed by a carbon dioxide adsorbing/desorbing liquid agent that contains a compound represented by general formula (1), so that a reaction product of the compound and the carbon dioxide is precipitated in the carbon dioxide adsorbing/desorbing liquid agent; and a step (B1) wherein the carbon dioxide is desorbed from the carbon dioxide adsorbing/desorbing liquid agent by subjecting the carbon dioxide adsorbing/desorbing liquid agent after the precipitation of the reaction product to a heat treatment. (Meanwhile, the cases where m is 0, p1 is 2, and two amino groups, to which p1 is attached, are arranged in the meta position to each other are excluded).
