摘要

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278.15~348.15 K

实验压力由低于大气压到最高6.5 MPa。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278.15 K、120 kPa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0.459 mol CO2 ·(mol IL)-1

接近理论最大吸收值0.5 mol CO2·(mol IL)-1。在较高压力下(3.9 MPa)最大CO2吸收量为1.894 mol CO2·(mol IL)-1。

Abstract

Experiments for the solubility and phase equilibrium of carbon dioxide in aqueous solution of 1-aminopropyl-3-methylimidazolium bromide([APMIm])with three water concentrations(16.04%

31.59% and 60.84%

mass fraction)

at 278.15—348.15 K and pressure up to 6.5 MPa were performed by using a high-pressure reaction cell based on an isochoric saturation technique.The results indicated that water concentration could greatly enhance the absorption capacity and increase the absorption rate of carbon dioxide in[APMIm] aqueous solution.For the 60.84% aqueous IL solution at 5℃ and 120 kPa

CO2 solubility was up to 0.459 mol CO2·(mol IL)-1

close to the theoretical maximum absorption capacity of 0.5 mol CO2·(mol IL)-1.Under a higher pressure(3.9 MPa)

maximum CO2 absorption was 1.894 mol CO2·(mol IL)-1.
