摘　　要：介绍了柴油氧化脱硫机理;综述了近年来国内外柴油氧化脱硫技术的研究进展,包括以双氧水、有机过氧化物为氧化剂的氧化脱硫技术,生物氧化脱硫技术,西南石油学院开发的直馏柴油催化氧化脱硫技术。分析了各种氧化脱硫技术的优缺点,认为以双氧水为氧化剂的氧化脱硫技术脱硫率和柴油收率都较高,但存在氧化剂成本高、氧化态硫化物出路等缺点;而催化氧化脱硫技术采用廉价的空气或氧气为氧化剂,柴油收率达93%以上,柴油质量指标能满足欧洲Ⅱ类标准,即硫含量小于300μg/g,因此,催化氧化脱硫技术将成为今后生产超低硫柴油的主要工艺之一。Mechanisms of diesel oxidation desulfurization were introduced and diesel oxidation desulfurization technologies at home and abroad were summarized in recently years, including the oxidation desulfurization technology with hydrogen peroxide or organic peroxides as oxidant, biooxidative desulfurization technology and catalytic oxidation desulfurization technology of straight - run diesel developed by SWPU, the advantages and disadvantages of all kinds of oxidation desulfurization technologies were analyzed, it is considered that the oxidation desulfurization technology with hydrogen peroxide as oxidant has some advantages such as high desulfurization rate and high yield of diesel, but high cost of oxidant and the treatment of oxidation state sulfur compounds are its disadvantages. Catalytic oxidation desulfurization technology with cheap air or oxygen as oxidant has the yield of diesel up to 93 %, the sulfur content of treated diesel can meet the Europe Ⅱ specification of less than 300μg/g, therefore catalytic oxidation desulfurization technology will become one of primary processes of producing ultra low sulfur diesel in the future.
