Nowadays, a continuously worldwide concern for development of process to produce ultra-low sulfur and nitrogen fuels have been emerged. Typical hydrodesulfurization and hydrodenitrogenation technology deals with important difficulties such as high pressure and temperature operating condition, failure to treat some recalcitrant compounds and limitations to meet the stringent environmental regulations. In contrary an advanced oxidation process that is ultrasound assisted oxidative desulfurization and denitrogenation satisfies latest environmental regulations in much milder conditions with more efficiency. The present work deals with a comprehensive review on findings and development in the ultrasound assisted oxidative desulfurization and denitrogenation (UAOD) during the last decades. The role of individual parameters namely temperature, residence time, ultrasound power and frequency, pH, initial concentration and types of sulfur and nitrogen compounds on the efficiency are described. What's more another treatment properties that is role of phase transfer agent (PTA) and solvents of extraction step, reaction kinetics, mechanism of the ultrasound, fuel properties and recovery in UAOD are reviewed. Finally, the required future works to mature this technology are suggested.
如今，全球对生产超低硫和氮燃料工艺的发展持续关注。典型的加氢脱硫和加氢脱氮技术面临诸如高压和高温操作条件、无法处理某些难降解化合物以及难以满足严格环境法规等重大难题。相反，一种先进的氧化工艺，即超声辅助氧化脱硫和脱氮，能在温和得多的条件下更高效地满足最新环境法规。本工作对过去几十年中超声辅助氧化脱硫和脱氮（UAOD）的研究成果及进展进行了全面综述。描述了诸如温度、停留时间、超声功率和频率、pH值、硫和氮化合物的初始浓度及类型等各个参数对效率的作用。此外，还综述了其他处理特性，即相转移剂（PTA）的作用、萃取步骤的溶剂、反应动力学、超声作用机理、燃料特性以及UAOD中的回收情况。最后，提出了使该技术成熟所需的未来工作建议。
