| 摘要 |
An absorption medium which comprises water, an amine (A) of the formula (I), where R is a n-alkyl radical having 1 to 4 carbon atoms, and an alkanolamine (B) which is a tertiary amine or a sterically hindered primary or secondary amine, has a high absorption capacity for CO2 at a high absorption rate. Using the absorption medium, during the absorption of acid gases from a gas mixture, even without addition of a solvent, a separation of the absorption medium into two liquid phases or the precipitation of a solid during the absorption of CO2 and the regeneration of the absorption medium may be avoided. |
