摘要 采用功能化离子液体支撑液膜进行CO_2的分离性能及促进传递机理研究,比较了阴离子种类、操作压力、操作温度及含水量对分离性能的影响。结果表明:此类弱碱性功能化离子液体通过可逆化学反应能够实现CO_2/N_2、CO_2/CH_4的有效分离。在40℃、CO_2偏压为10 kPa条件下,[N_(2224)][maleate]离子液体支撑液膜对CO_2/N_2、CO_2/CH_4的分离因子分别高达250、220以上,有望通过固定化载体膜进一步增强稳定性,实现CO_2分离的工业化应用。 采用功能化离子液体支撑液膜进行CO<sub>2</sub>的分离性能及促进传递机理研究,比较了阴离子种类、操作压力、操作温度及含水量对分离性能的影响。结果表明:此类弱碱性功能化离子液体通过可逆化学反应能够实现CO<sub>2</sub>/N<sub>2</sub>、CO<sub>2</sub>/CH<sub>4</sub>的有效分离。在40℃、CO<sub>2</sub>偏压为10 kPa条件下,[N<sub>2224</sub>][maleate]离子液体支撑液膜对CO<sub>2</sub>/N<sub>2</sub>、CO<sub>2</sub>/CH<sub>4</sub>的分离因子分别高达250、220以上,有望通过固定化载体膜进一步增强稳定性,实现CO<sub>2</sub>分离的工业化应用。
