摘　　要：首先介绍了加氢催化脱硫和其他脱硫技术的特点,综述了近年来国内外利用离子液体在萃取脱硫、萃取脱硫与氧化脱硫耦合、萃取脱硫与生物脱硫耦合等方面的研究。认为离子液体萃取脱硫具有操作简便、可循环使用、无需氢气、环境友好、能深度脱硫等特点,是一项具有广阔发展前景的技术。若要实现该技术的工业化应用,还需进一步加强离子液体在合成工艺、脱硫选择性及回收再生等方面的研究。Catalytic hydrodesulfurization and the other desulfurization of fuel oil were introduced. Researches for extractive desulfurization, coupling of extractive and oxidative desulfurizations, and coupling of extractive and biologic desulfurizations at room temperature with ionic liquids as extractants were reviewed. Trend for extractive desulfurization of fuel oil with ionic liquids was forecasted. Technology of using ionic liquids in extractive desulfurization of fuel oil possesses advantages of mild operation conditions, without hydrogen consumption, recycling of ionic liquid, environmental friendly and deep desulfurization capacity. For the sake of commercialization of the desulfurization technology, synthesis of appropriate ionic liquid extractant, their selectivity in extractive desulfurization and recycling of the used ionic liquids should further be concentrated on.
