Beschreibung
Zusammenfassung:	An aqueous CO2 absorbent comprising a combination of a sterically hindered amine and a monoalkanolamine, wherein the concentration of the sterically hindered amine is from 10 to 35 % by weight and the concentration of the monoalkanolamine is from 10 to 35 % by weight, is described. Additionally, a method for removal of CO2 from an exhaust gas using the absorbent, is described. L'invention porte sur un absorbant aqueux de CO2 comprenant une association d'une amine stériquement encombrée et d'une monoalcanolamine, la concentration de l'amine stériquement encombrée étant de 10 à 35 % en poids et la concentration de la monoalcanolamine étant de 10 à 35 % en poids. De plus, l'invention porte sur un procédé pour l'élimination de CO2 à partir d'un gaz brûlé à l'aide de l'absorbant.
