Abstract:
A carbon dioxide absorbent of an embodiment includes a chain amine, a cyclic amine, and an acid. The chain amine is a compound expressed by Formula (1) of FIG.  1 . R 1  in Formula (1) is hydrogen or an alkyl chain having at least one hydroxyl group and 1 to 7 carbon atoms. R 2  in Formula (1) is an alkyl chain having at least one hydroxyl group and 1 to 7 carbon atoms. R 3  in Formula (1) is hydrogen, a straight alkyl chain having 1 to 7 carbon atoms, a branched alkyl chain having 1 to 7 carbon atoms, or a cyclic alkyl chain having 5 to 7 carbon atoms.

Claim (Index 10):
An apparatus of separating and recovering carbon dioxide, the apparatus using the carbon dioxide absorbent according to  claim 1 , the carbon dioxide absorbent being a carbon dioxide unabsorbed carbon dioxide absorbent, the apparatus comprising:\n an absorption tower configured to separate and recover carbon dioxide from gas containing carbon dioxide by contacting the gas containing carbon dioxide with the carbon dioxide unabsorbed carbon dioxide absorbent to allow carbon dioxide to be absorbed in the carbon dioxide unabsorbed carbon dioxide absorbent and a carbon dioxide absorbed carbon dioxide absorbent is obtained; and a regeneration tower configured to regenerate the carbon dioxide absorbed carbon dioxide absorbent by desorbing carbon dioxide from the carbon dioxide absorbed carbon dioxide absorbent which has absorbed carbon dioxide.
