Abstract: A description is given of an absorption medium for deacidifying fluid stream s which has improved oxidation stability and comprises at least one aliphatic amine, in particular an alkanolamine, and at least one non-hydroquinoid antioxidant. The absorption medium serves for deacidifying a fluid stream, in particular an oxygen-containing fluid stream, the fluid stream being brought into intimate contact with the absorption medium in at least one absorption step.

Abstract: The invention relates to a method for the removal of carbon dioxide from a gas flow, in which the partial pressure of the carbon dioxide in the gas flow is less than 200 mbar, whereby the gas flow is brought into contact with a liquid absorption agent, comprising an aqueous solution (A) of a tertiary aliphatic amine and (B) an activator of general formula R 1 -NH-R 2 -NH 2 , where R 1 =C 1 -C 6 alkyl and R 2 =C 2 -C 6 alkylene. The method is particularly suitable for treatment of flue gases and also relates to an absorption agent.
