Alkali-carbonate-based carbon dioxide absorbent containing added sterically hindered cyclic amines, and method for removing carbon dioxide removing using same

摘要

The present invention relates to a carbon dioxide absorbent, and more particularly, to an alkali-carbonate-based carbon dioxide absorbent containing added sterically hindered cyclic amines, and to a method for removing carbon dioxide using same. By adding sterically hindered cyclic amines to an alkali carbonate material, the rate of carbon dioxide absorption is increased, renewable energy is reduced, and salt production and phase separation do not occur.
