Alcohol amine solutions have a high absorption capacity and rate for CO 2 capture, however, there are some shortcomings such as high energy-consumption and low stability. To enhance CO 2 capture performance of aqueous MEA, a functional ionic liquid ([NH 2 e-mim][BF 4 ]) was introduced based on the advantages for CO 2 capture. Absorbents were prepared with the molar concentration ratio of [NH 2 e-mim][BF 4 ] to the 30 vol% aqueous MEA of 010, 1:9, 2:8, 3:7, 4:6 and 6:4. The density and the viscosity of the investigated absorbents were measured a...
