| 摘 要： | 选用不同种类的室温型离子液体（RTILs）与胆碱脯氨酸离子液体进行混合分别制得Choline]Pro]/EMIm]N（CN）2]、Choline]Pro]/bmim]PF6]以及Choline]Pro]/HMIm]NTf2]混合离子液体，并将其应用于离子液体支撑液膜（SILMs）。考察操作温度、操作压差、RTILs种类和含量对SILMs分离CO2/N2性能的影响。结果表明胆碱脯氨酸/RTILs系列SILMs的CO2通量在343.3～1936.9 barrer之间变化并且CO2/N2选择性为10.3～34.8。对CO2膜过程内在机制探索表明随着HMIm]NTf2]离子液体在混合离子液体中比例的增加，总阻力1/Km会呈现先降低后升高的趋势。与实验现象中随着HMIm]NTf2]离子液体在混合离子液体中比例的增加CO2先升高后降低相符。

| Abstract: | Three mixed ionic liquids (Choline]Pro]/EMIm]N(CN)2], Choline]Pro]/bmim]PF6] and Choline]Pro]/HMIm]NTf2]) were prepared by mixing room temperature ionic liquids (RTILs) with Choline]Pro]. They were used to prepare SILMs by the impregnation method. Effects of operating temperature, pressure, type and content of RTILs on CO2/N2 separation performance of SILMs were investigated. The results showed that the CO2 permeability of the SILMs changed between 343.3-1936.9 barrer and CO2/N2 selectivity was in range of 10.3-34.8. Non-equilibrium thermodynamics was used to analyze CO2 transport mechanism in SILMs. The overall resistance showed a trend from decline to rise by increasing the proportion of HMIm]NTf2] in the mixed ILs, which was in accordance with CO2 permeability in SILMs. |
