离子液体在燃料油脱硫中的研究进展

Research progress in desulfurization of fuel oil by ionic liquids

在简单对比了催化加氢和非催化加氢技术在燃料油脱硫方面应用的基础上,分析了非催化加氢技术的研究状况,论述了几种离子液体在直接萃取、氧化脱硫和烷基化脱硫等非催化加氢中的研究进展,并对几种离子液体的脱硫效果做了一定量的汇总。针对氧化脱硫过程中双氧水消耗量多、成本高等问题,对功能化离子液体在氧气氧化脱硫过程中的应用做了介绍,并对其今后的研究方向和内容做了展望。

Based on a simple comparison of the applications of non-catalytic hydrogenation and catalytic hydrogenation technology in fuel oil desulfurization,the research status of non-catalytic hydrogenation technology was reviewed.Then the research progress in applications of several ionic liquids in non-catalytic hydrogenation desulfurizations,such as direct extraction,oxidative desulfurization,and alkylation desulfurization,was discussed.A certain amount of summary for the desulfurization effect of such ionic liquids was made.Then,for the problems of more H2O2′s consumption and high cost etc.,the application of the functionalized ionic liquids in oxygen oxidative desulfurization process was introduced.The research direction and contents in future were also prospected.
