Beschreibung
Zusammenfassung:	The present invention relates to a carbon dioxide absorbent comprising an oxygen-containing diamine, a cyclodiamine and a polyalkylene glycol dialkyl ether. The carbon dioxide absorbent according to the present invention can improve the carbon dioxide absorption capacity, absorption rate and regeneration performance thereof simultaneously by using the oxygen-containing diamine as a main absorbent, the cylodiamine as a rate enhancer, and the polyalkylene glycol dialkyl ether as a fine disproportionation agent and a regeneration promoter.
