摘　　要：由于成本低、脱硫率高等优点,氧化脱硫可成为未来非加氢方法生产超低硫清洁燃料油的主要技术之一。综述了国内外一些氧化脱硫机理的现状,如用不同催化剂将含硫油品氧化成不同的中间体的催化氧化脱硫、过氧中间体与含硫化合物发生基元反应的催化氧化离子液体氧化脱硫、通过不同光敏剂发生反应的光化学氧化脱硫、以电化学接触含硫化合物电解脱硫的电化学氧化脱硫、以微生物或者微生物所含的酶为催化剂生物氧化脱硫等,并且指出目前机理研究尚有不足,有些反应机理并不明确,还有待深入研究。Due to the several advantages,such as low cost and high desulphurization rate,the oxidation desulphurization may become one of the main techniques of producing super low sulfur content clean fuel oil without hydrogenation in the future.Various mechanisms of oxidation desulfurization for oil are summarized,including catalytic oxidation desulfurization which employs various catalysts to oxidize the sulfur-contained oil into different intermediates,catalytic oxidation ionic liquids desulfurization which employs the peroxy-intermediates and sulfur-contained compound to react with each other by elementary reaction,photochemical oxidation desulfurization which adopts various photo-sensitizer,electrochemical oxidation desulfurization and biological oxidation desulfurization which uses microorganism or enzyme as catalysts,etc.It is pointed that the studies on mechanisms at present are insufficient,and some of them are not clear and definite,which need to be studied in depth.
