An absorbent liquid for improved absorption capacity for CO2 in a gas due to the presence of an activator for CO2 absorbent from the gas, the absorption liquid comprising a mixture of one or more tertiary alkanolamines and an activator of CO2 absorption by the tertiary alkanolamine, which activator has the general formula Y-(CpH2p)-NHZ wherein Y is a monovalent radical selected from the group consisting of piperazyl, piperidinyl, furyl, tetrahy-drothienyl and -OR2 radicals, Z is an R2 radical or hydrogen, R2 is a monovalent hydrocarbon residue, and p is an integer from 1 to 6. Also a process for using such absorbent liquid for improved CO2 absorption from a gas.
