本文首次引入四种二胺单羧酸盐质子离子液体（PIL）制备支撑型离子液体膜（SILM），并研究了在增湿条件下CO2/N2和CO2/CH4气体对的选择性分离。研究了跨膜压力和温度对CO2渗透性和CO2/N2、CO2/CH4气体对选择渗透性的影响。结果表明，含水量为15%的负载型PIL在潮湿条件下的CO2渗透率明显高于干燥条件下的纯PIL。膜的通透性随跨膜压的降低而增加，表现出易化转运膜的典型特征。随着温度的升高，CO2的渗透率增加，而CO2/N2和CO2/CH4的选择渗透率降低。最高CO2/N2选择性为151，最高CO2/CH4选择性为72。这些PIL被发现是可调的和选择性的载体CO2在水的存在下，和支撑质子-离子液体膜相比，具有竞争性的渗透性和更高的选择渗透性。
In this work, four diamine-monocarboxylate-based protic ionic liquids (PILs) were firstly introduced to prepare supported ionic liquid membranes (SILMs) and the selective separation of CO2/N2and CO2/CH4gas pairs in these SILMs under humidified condition were investigated. The effects of transmembrane pressure and temperature on the permeablity of CO2and the permselectivity of CO2/N2and CO2/CH4gas pairs were also studied. It is found that the supported PILs with 15 wt% water exhibit much higher CO2permeabilities under humidified conditon than those pure PILs under dry condition. The permeability increases with the decreasing transmembrane pressure, indicating a typical feature of facilitated transport membrane. The permeability of CO2increases with the increasing temperature whereas the permselectivity of CO2/N2and CO2/CH4decreases at the same time. The highest CO2/N2selectivities obtained is 151, and the highest CO2/CH4selectivities is 72. These PILs is found to be tunable and selective carriers of CO2in the presence of water, and the supported protic-ionic liquid membranes exhibit competitive permeability and higher permselectivity in comparison with the supported aprotic- ionic- liquid membranes.
