PROCESS FOR ABSORBING CO2 FROM A GAS MIXTURE WITH AN ABSORPTION MEDIUM COMPRISING AMINES |
摘要 |
<p>An absorption medium comprising water and at least one amine of formula (I) where R2 is hydrogen or an alkyl radical having 1 to 4 carbon atoms, R2 is an alkyl radical having 1 to 4 carbon atoms, R3 and R5 are each independently alkyl radicals having 1 to 6 carbon atoms and R4 and R6 are each independently hydrogen or alkyl radicals having 1 to 6 carbon atoms where R3 and R4 may combine to form the bridging radical—(CH2)n—,—CH2CH2OCH2CH2—or—CH2CH2NR7CH2CH2—with n=2 to 5 and R2=hydrogen or an alkyl radical having 1 to 6 carbon atoms, brings about an improved CO2 absorption capacity in the absorption of CO2 from a gas mixture by contacting the gas mixture with the absorption medium.</p> |
