Abstract: The invention relates to an absorption agent for removing acidic gases from a fluid flow, comprising an aqueous solution (A) of an alkali metal salt of an N,N-di-C1-C4-alkyl-amino carbolic acid and (B) N-hydroxyethylpiperazine. The absorption agent comprises a lower vapor pressure and increased resistance to oxygen. Preferable fluid flows are combustion exhaust or biogas.

Abstract: The present invention relates to a method for separating at least one acid gas from a gas mixture, containing the step of bringing the gas mixture into contact with a porous metal-organic framework, the framework adsorbing the at least one acid gas, and the framework containing at least one at least bidentate organic compound coordinatively bonded to at least one metal ion, characterized in that the porous metal-organic framework is impregnated with an amine suitable for gas scrubbing. The invention further relates to such impregnated metal-organic frameworks.
