With increasingly stringent emission limits on sulfur and sulfur-containing substances, the reduction and removal of sulfur compounds from fuels has become an urgent task. Emissions of sulfur-containing compounds pose a significant threat to the environment and human health. Ionic liquids (ILs) have attracted much attention in recent years as green solvents and functional materials, and their unique properties make them useful alternatives to conventional desulfurization organic solvents. This paper reviews the advantages and disadvantages of traditional desulfurization technologies such as hydrodesulfurization, oxidative desulfurization, biological desulfurization, adsorptive desulfurization, extractive desulfurization, etc. It focuses on the synthesis of ionic liquids and their applications in oxidative desulfurization, extractive desulfurization, extractive oxidative desulfurization, and catalytic oxidative desulfurization, and it analyzes the problems of ionic liquids that need to be solved urgently in desulfurization, looking forward to the development of sulfuric compounds as a kind of new and emerging green solvent in the field of desulfurization.
随着对硫和含硫物质排放限制的日益严格，减少和去除燃料中的硫化合物已成为一项紧迫的任务。含硫化合物的排放对环境和人类健康构成了重大威胁。近年来，离子液体（ILs）作为绿色溶剂和功能材料引起了广泛关注，其独特的性质使它们成为传统脱硫有机溶剂的有用替代品。本文综述了加氢脱硫、氧化脱硫、生物脱硫、吸附脱硫、萃取脱硫等传统脱硫技术的优缺点。重点介绍了离子液体的合成及其在氧化脱硫、萃取脱硫、萃取氧化脱硫和催化氧化脱硫中的应用，并分析了离子液体在脱硫中急需解决的问题，期待将硫酸化合物作为一种新型的、有前途的绿色溶剂应用于脱硫领域。
