摘要:

离子液体(ILs)作为一种新型的绿色溶剂在吸收和分离一氧化碳(CO)方面显示出了独特的优异性和潜在的应用价值。对近年来ILs参与CO吸收分离的研究工作进展进行了综述,主要包括常规ILs、阴离子功能化ILs、ILs/Cu (Ⅰ)盐和ILs支撑液膜。重点论述了CO在ILs中的溶解度及对其他气体的选择性,并与ILs吸收分离二氧化碳(CO2)性能进行了比较;着重讨论了阴阳离子种类、取代基类型、温度、压力等因素对ILs吸收分离CO性能的影响,并介绍了ILs吸收CO的机理。最后,对设计合成新型功能化ILs应用于高效吸收分离CO提出了一些建议。

Abstract:

As a new type of green solvent, ionic liquids (ILs) have shown unique properties and potential application value in carbon monoxide (CO) absorption and separation. In this paper, the recent research progress of CO absorption and separation by ILs has been reviewed, including the traditional ILs, anion functionalized ILs, ILs/ Cu(Ⅰ) salts and supported IL membranes (SILMs). The solubility of CO in ILs and the selectivity to other gases are mainly discussed, which is compared to the performance of carbon dioxide (CO2) absorption by ILs. The effect of the type of anion, cation, and substituent, temperature and pressure on the ability of CO absorption and separation by ILs was summarized, and the mechanism of CO absorption by ILs was introduced. Finally, some suggestions on the design and synthesis of new functional ILs for the efficient absorption and separation of CO are put forward.

Key words: ionic liquids, carbon monoxide, absorption, separation
