摘要： An absorbent for removing carbon dioxide from a fluid stream, comprising an aqueous solution a) of an amine of the general formula (I) in which R1, R2 and R3 are each independently selected from C1-4-alkyl and C1-4-hydroxyalkyl; each R4 is independently selected from hydrogen, C1-4alkyl and C1-4-hydroxyalkyl; each R5 is independently selected from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl; X is OH or NH(CR1R2R3); m is 2, 3, 4 or 5; n is 2, 3, 4 or 5; and o is 0 or 1; and b) at least one activator selected from b1) a sterically unhindered primary amine and/or a sterically unhindered secondary amine; and a carboanhydrase. The absorbent allows rapid absorption of carbon dioxide from fluid streams.
