这篇选择性的评论讨论了非加氢脱硫工艺，特别是氧化脱硫，用于制造超清洁燃料。运输燃料的环境法规越来越严格，各种燃料中的法定硫含量在2005年已降至10 ppm以下，并且在不久的将来还会更低。然而，常规加氢脱硫方法是否能够提供硫含量小于5 ppm的燃料存在相当大的疑问。本文综述了非加氢脱硫技术，特别是氧化脱硫技术的最新进展以及我们的最新研究成果。审查包括以下三个部分。(I)介绍了燃料中各种含硫化合物的氧化反应性、各种氧化剂-催化剂体系的氧化反应和氧化机理。(II)介绍了轻柴油、煤油、减压瓦斯油等各种实用燃料的氧化情况，并对各种燃料氧化脱硫工艺的潜力进行了评价。(III)介绍了各种燃料中氧化硫化合物的脱除方法。
This selective review discusses nonhydrogenation desulfurization processes, particularly oxidative desulfurization, for the manufacture of ultra clean fuels. The environmental regulations for transportation fuels are becoming more and more severe, and the statutory sulfur content in various fuels was reduced to below 10 ppm in 2005, and will be lower in the near future. However, there is considerable doubt whether conventional hydrodesulfurization processes can provide fuels with sulfur content less than 5 ppm. This review describes recent advances in nonhydrogenation desulfurization processes, particularly oxidative desulfurization, as well as our latest research results. The review consists of three sections as follows. (I) The oxidation reactivities of various sulfur- containing compounds present in fuels, oxidation and oxidative mechanisms for various oxidant-catalyst systems are introduced. (II) The oxidation of various practical fuels such as light gas oil, kerosene, and vacuum gas oil, and others are described; and the potential of various oxidative desulfurization processes for the fuels are evaluated. (III) Removal methods of oxidized sulfur compounds in various fuels are described.
