Abstract:

1-氨丙基-3-甲基咪唑溴盐([APMIm])对CO2等酸性气体具有较强的选择性吸收性能,在能源及环保领域有较好应用前景。运用等容饱和吸收法在高压不锈钢反应釜中测得CO2在3种不同含水量的1-氨丙基-3-甲基咪唑溴盐水溶液中的溶解度数据,实验的温度范围为278.15~348.15K,实验压力由低于大气压到最高6.5MPa。实验结果表明,当水的质量分数达到60.84%以上,离子液体水溶液吸收CO2的能力和速率才会得到显著提升。尤其值得注意的是,在278.15K、120kPa达到吸收平衡时,CO2在含水质量分数为60.84%的1-氨丙基-3-甲基咪唑溴盐水溶液中的溶解度达到0.459molCO2·(molIL)-1,接近理论最大吸收值0.5molCO2·(molIL)-1。在较高压力下(3.9MPa)最大CO2吸收量为1.894molCO2·(molIL)-1。
