Abstract: The present application relates to a method for adding proton donor mixture to decrease renewable energy after absorption of an amine absorbent which is a carbon dioxide absorbent, for absorbing carbon dioxide using the same, and to a regenerating method using the same. The regenerating method comprises a step for preparing a proton donor mixture using amine and a proton donor precursor; a step for preparing an absorbent by mixing amine and the proton donor mixture; a step for absorbing carbon dioxide moving from a lower part of an absorption tower to an upper part after injecting the absorbent into a carbon dioxide treatment device comprising an absorption tower and a regeneration tower, and then moving the absorbent counter-currently from the lower part of the absorption tower to the upper part; and a step for regenerating the absorbent by moving the absorbent gone through the step for absorbing carbon dioxide to the regeneration tower. Because the absorbent in which the proton donor mixture is mixed with amine represents high regeneration efficiency even at low temperature because the proton donor mixture gives a proton in the case of regeneration, the absorbent can be repetitively used due to high thermal stability and has long lifetime.
