Liquid absorbing acid gas compounds presenting an improved CO.sub.2 absorption capacity, said absorbing liquid containing one or a plurality of tertiary alkanolamines and a CO.sub.2 absorption activator. The activator is comprised of at least one amino compound selected among polyalkylene-polyamines, alkylenediamines or cycloalkylenediamines, the aminoalkylated compounds of heterocycles such as piperazine, piperidine, furan, thiophene, tetrahydrofuran and tetrahydrothiophene, the alkoxyalkylamines and the alkylmono-alkanolamines having an alkyl residue in at least C.sub.2. Application of said absorbent liquid to the deacidification of gases containing CO.sub.2 and optionally other acid gas compounds, particularly H.sub.2 S and/or COS.
