摘要
简述并比较了各种燃油脱硫方法,如加氢脱硫、生物脱硫、吸附脱硫、萃取脱硫、萃取氧化脱硫的优缺点,重点从离子液体脱硫的影响因素、脱硫机理、脱硫方法及离子液体的负载等几个方面综述了离子液体在油品脱硫中的应用。离子液体具有独特的化学结构和优良的物化性质,应用于油品脱硫时有着其它传统有机溶剂无可比拟的优势,脱硫效果理想,尤其是与其它工艺(如氧化法)相结合时,脱硫效果更佳。由过去几十年里离子液体的迅猛发展可以预见更多由离子液体参与的高效、绿色环保及成本低廉的脱硫过程。
This paper briefly introduced advantages and disadvantages of several fuel desulfurization ways such as hydrodesulfurization,biodesulfurization,adsorption,extractive desulfurization as well as extractive-oxidative desulfurization with special emphasis on the role of ionic liquids（ILs）. Effects,mechanism,desulfurization methods and mobilization ways of ILs were thoroughly diccussed. ILs had unique chemical structure and good characters as unexampled advantages in desulfurization,especially combined with other methods. With rapid progress of ILs,more reliable,cheap,and effective desulfurization process could be anticipated.
