Absorbing solution, method for preparing an absorbing solution, use of the absorbing solution and method for activating an absorbing solution

摘要

Absorption liquid comprises an aqueous solution of detergent-active substance based on amines or ethanol amines, amino acid salts and/or potash, and an activating additive, which is an inorganic catalyst . Independent claims are included for: (1) the activation of a solvent to provide the absorption liquid, comprising adding the activating additive to the solvent comprising an aqueous solution of the detergent-active substance, for accelerating a selective absorption of carbon dioxide from the flue gas of a combustion plant; and (2) producing the absorption liquid comprising adding an aqueous solution of the detergent-active substance into the aqueous solution of the activating additive.
