摘要: 低共熔溶剂作为近十年来迅速发展的一类新型绿色溶剂,不仅具备离子液体的优点,而且原料价廉易得、合成条件简单、萃取脱硫效果好,已成为继离子液体用于车用燃料脱硫研究之后又一新的研究热点。本文根据合成低共熔溶剂的盐与氢键供体(或水合盐)的不同,对用于车用燃料脱硫的低共熔溶剂进行了分类总结,简述了低共熔溶剂的物化性质,介绍了低共熔溶剂用于车用燃料脱硫的方法及研究进展,对比了低共熔溶剂对不同含硫化合物的脱除效果,归纳了低共熔溶剂的萃取脱硫和氧化萃取脱硫机理。最后针对低共熔溶剂用于车用燃料脱硫中存在的选择性低、循环再生等关键问题,指出了其研究发展方向应是通过开发具有萃取脱硫高选择性的低共熔溶剂以及寻找新型绿色环保的低共熔溶剂脱硫方法来实现深度脱硫。

Abstract: Deep eutectic solvents are novel environment friendly solvents that have developed rapidly in the past ten years. They not only have the advantages of ionic liquids, but also are low-cost, easy to obtain and synthesize, and are good in extraction desulfurization, which have become a new research hotspot in the desulfurization of vehicle fuel after the ionic liquids. In this paper, the deep eutectic solvents used in the vehicle fuel desulfurization were classified based on the difference of the quaternary ammonium salt and hydrogen bond donor (or hydrated salt). The physicochemical properties of eutectic solvent were briefly described. The desulfurization method and research progress of the deep eutectic solvents used for desulfurization of vehicle fuel were introduced. The removal efficiencies of deep eutectic solvent on different sulfur compounds were compared, and the mechanism of extraction desulfurization and oxidation extraction were summarized. Finally, in view of the key problems such as low selectivity and regeneration in desulfurization process, it is proposed that one of the prospective research issues is to find new DESs with high selectivity or give recommendation for new green desulfurization method to achieve deep desulfurization.

Key words: deep eutectic solvents, vehicle fuel, desulfurization, mechanism
