| 摘 要： | 利用浸渍法将NH3P-mim]BF4]和MEA]L两种离子液体负载到AC、Al2O3和MCM-41上，考察了对CO2的吸附性能，确定了NH3P-mim]BF4]/AC对CO2的吸附性能最优。并对NH3P-mim]BF4]/AC考察了不同负载量、不同温度下对CO2的吸附性能，确定了固载离子液体对CO2的吸附容量随着负载量的增加而增加，且30℃是固载离子液体吸附CO2的最佳温度，吸附容量达到0.063 mmol CO2·(g SILP)-1。对NH3P-mim]BF4]/AC进行红外和热重两种表征，确定了负载离子液体的结构以及在50℃以下优良的热稳定性。

| Abstract: | Two kinds of ionic liquids (NH3P-mim]BF4] and MEA]L) were supported to AC, Al2O3 and MCM-41 by soaking method. NH3P-mim]BF4]/AC was confirmed to have the better CO2 adsorption capacity. Using NH3P-mim]BF4]/AC, CO2 adsorption capacity was tested under the condition of different amount of supported ionic liquids and different temperature. The results show that CO2 adsorption capacity increases with the amount of supported ionic liquids increasing, and 30℃ was the optimum temperature, with an CO2 adsorption capacity of 0.063 mmol CO2·(g SILP)-1. The structure of the NH3P-mim]BF4]/AC was confirmed by FT-IR and thermogravimetry characterization, the latter shows that it has excellent thermostability wthin below 50℃. |
