CO2 ABSORBENT BASED ON ALKALI CARBONATE SOLUTION PROMOTED BY HINDERED CYCLIC AMINES AND CO2 REMOVING METHOD USING THE SAME

摘要

PURPOSE: A carbon dioxide absorbing agent containing hindered cyclic amines and a method for eliminating carbon dioxide using the same are provided to improve the speed of a carbon dioxide absorbing process and reducing regenerated energy. CONSTITUTION: A method for eliminating carbon dioxide using a carbon dioxide absorbing agent containing hindered cyclic amines includes the following: A carbon dioxide absorbing agent includes 16 wt% or less of alkaline carbonate and 10 wt% or less of hindered cyclic amines. The carbon dioxide absorbing agent is in contact with gas containing carbon dioxide(S110). The carbon dioxide is absorbed to the carbon dioxide absorbing agent(S120). The carbon dioxide absorbing agent is regenerated(S130).
