摘要:

低碳烯烃/烷烃的高效分离是石油化工领域可持续发展的关键过程之一,传统的低温精馏过程选择性低、能耗大。离子液体作为一种结构可调的绿色溶剂为低碳烃的高效分离提供了新的思路。本文综述了近年来国内外离子液体在低碳烯烃/烷烃分离中的研究进展,总结了常规离子液体、功能化离子液体以及含过渡金属的离子液体在低碳烯烃/烷烃分离中的应用,阐明了离子液体中阴阳离子、功能化基团、过渡金属与低碳烯烃相互作用的机理,着重介绍了合成金属功能化离子液体、添加金属盐、添加金属纳米粒子3种向离子液体中引入过渡金属方式的特点以及过渡金属的种类、比例,有机配体的类型对离子液体烯烃/烷烃分离性能的影响,并探讨了该方向的研究和发展趋势。

Abstract:

Separation of olefin/paraffin is one of the vital important processes in chemical industry. The traditional cryogenic distillation usually exhibits low selectivity and high energy consumption. As the “green solvents”, ionic liquids (ILs) have tunable structures and high olefin solubility, which provide a novel route for efficient and energy-saving separation of olefin/paraffin. In this paper, the recent advances on ILs for the separation of olefin/paraffin were summarized. The separation performances of conventional ILs, functionalized ILs and silver-based ILs were emphasized and the effects of cations, anions, functional groups and mental ions on separation performance were discussed. The characteristics of three ways that introducing transition metals into ionic liquids, as well as the influence of the proportion of transition metals and the types of organic ligands on the separation performance of ionic liquids were emphatically introduced. Meantime, the future research challenges and perspectives of ILs in olefin/paraffin separation have been also posed.

Key words: light hydrocarbons, ionic liquid, olefin, paraffin, separation, complexation
