Abstract: Disclosed is an absorbent for removing carbon dioxide from a fluid flow, said absorbent comprising an aqueous solution of: a) an amine of general formula (I), formula (I) wherein R1, R2 and R3 are selected independently from one another from C1-4- alkyl and C1-4-hydroxyalkyl, R4 in each case is selected independently from hydrogen, C1-4-alkyl and C-4-hydroxyalkyl, R5 in each case is selected independently from hydrogen, C-4-alkyl and C1-4-hydroxyalkyl, X stands for OH or NH(CR1R2R3), m stands for 2, 3, 4 or 5, n stands for 2, 3, 4 or 5, and o stands for 0 or 1; and b) at least one activator selected from 5-, 6-, or 7-membered heterocycles with an NH group in the ring and one or to other heteroatoms in the ring, which are selected from nitrogen and oxygen. The absorbent enables a rapid absorption of carbon dioxide from fluid flows.
