摘要/Abstract

摘要： 由于操作条件温和、成本相对较低、脱硫率高以及绿色环保等优点，氧化脱硫被认为是非加氢脱硫技术中降低燃料油中高硫含量的主要技术之一。本文综述了近些年来国内外关于燃料油氧化脱硫机理的研究进展，详细叙述了使用不同氧化剂（H₂O₂、油溶性氧化剂、空气、氧气以及固体氧化剂）催化氧化脱硫机理和离子液体中的氧化脱硫机理，简要介绍了低共熔溶剂中的氧化脱硫机理、超声辅助氧化脱硫机理、光催化氧化脱硫机理以及电化学氧化脱硫机理，并对氧化脱硫机理的研究方向提出了见解。加深对氧化脱硫机理的研究将有利于寻求合适的催化剂和反应条件，为更好地指导燃料油以及其他油品深度脱硫的进行提供理论基础，对实际生产也具有重要的理论指导意义。

Abstract: Due to the advantages of mild operating conditions, relatively low cost, high desulfurization rate and green environmental protection, oxidative desulfurization is considered to be one of the main techniques for reducing the high sulfur content of fuel oil among non-hydrodesulfurization techniques. In this paper, the research progress of the oxidative desulfurization mechanism of fuel oil at home and abroad in recent years is reviewed. The mechanism of catalytic oxidative desulfurization using different oxidants (such as hydrogen peroxide, oil-soluble oxidants, air, oxygen and solid oxidants) and the mechanism of oxidative desulfurization in ionic liquids are described in detail. The mechanism of oxidative desulfurization in deep eutectic solvents, ultrasound-assisted oxidative desulfurization mechanism, photocatalytic oxidative desulfurization mechanism and electrochemical oxidative desulfurization mechanism are briefly introduced. Moreover, my own opinions on the research direction of oxidative desulfurization mechanism are put forward. Deepening the research on the mechanism of oxidative desulfurization will be beneficial to find suitable catalysts and reaction conditions, provide a theoretical basis for better guiding the deep desulfurization of fuel oil and other oils. It also has important theoretical guiding significance for actual production.
