摘　　要：柴油作为热值高、消耗率低的石油馏分燃料,可搭配大功率机械的使用标准,在传统能源中使用占比越来越高,被广泛应用于各种大型器械运作和生产中。随着柴油消耗的增多,柴油使用的污染问题也开始得到重视。硫作为主要污染物,在新的柴油标准中有了更高的要求,有必要对各脱硫方法进行深入探讨和工艺创新。传统加氢脱硫局限性过大,因此开发了各种非加氢脱硫方式进行脱硫研究,旨在研发出高效率和环境友好的绿色脱硫方式。综述了各种常规脱硫方法的优点和不足,归纳了生物酶催化氧化脱硫的研究现状和国内外最新进展,重点讨论了生物酶的各种脱硫方式的反应机理和具体研究实例,并对未来新型脱硫方式研究前景进行展望。As a petroleum distillate fuel with high calorific value and low consumption rate,diesel can be matched with the use standard of high-power machinery.It accounts for an increasing proportion in traditional energy.It is widely used in the operation and production of various large-scale equipment.With the increase of diesel consumption,the pollution problem of diesel has begun to drawn attention.Sulfur,as the main pollutant,has higher requirements in the new diesel standard.It is necessary to explore the desulfurization methods and innovate the technology.Traditional hydrodesulfurization has a number of limitations,so a variety of non hydrodesulfurization methods have been developed for desulfurization research,aiming to develop a green desulfurization method with high efficiency and environmental friendliness.This paper mainly summarizes the advantages and disadvantages of various conventional desulfurization methods.The research status and the latest progress of enzyme catalyzed oxidative desulfurization at home and abroad were reviewed.The reaction mechanism and specific research examples of various desulfurization methods were discussed.On this basis,the various methods were summarized and analyzed,and the author’s point of view and the prospect of new desulfurization methods in the future were put forward.
