摘要：

This work focuses on selecting new absorbents for CO2 capture. Absorption of CO2 was studied at 40 degrees C using both single and mixed amine-based absorbents. The experimental results show that most absorbents tested have a poorer performance than MEA, but that aqueous AEEA might be a possible contender. In addition to the absorption measurements, the VLE of CO2 in the selected absorbent, the aqueous 2.9 M AEEA, were studied at 40 and 120 degrees C. The equilibrium partial pressures of CO2 in the aqueous 2.9 M AEEA at the temperature of removal (40 degrees C) and that of regeneration (120 degrees C) are lower than for aqueous 5.0 M MEA, but the maximum net cyclic capacity is somewhat higher.
