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 its low cost and high desulfurization rate, oxidative desulfurization can become one of the main technologies for the future non-hydrogenation of ultra-low sulfur clean fuel oil. The current status of some oxidative desulfurization mechanisms at home and abroad are reviewed, such as catalytic oxidative desulfurization with different catalysts for the oxidation of sulfur-containing oils to different intermediates, catalytic oxidation of ionic liquids by oxidative desulfurization of peroxygen intermediates with sulfur-containing compounds , Photochemical oxidative desulfurization by different photosensitizers, electrochemical oxidative desulfurization by electrochemical contacting with sulfur compounds by electrolytic desulfurization, biological oxidative desulfurization by enzymes contained by microorganisms or microorganisms, etc., and pointed out that the current mechanism research is still insufficient , Some of the reaction mechanism is not clear, yet to be further studied.
