The article reveals the importance of the role of diesel fuel (DF) in Russian economy. In this regard, the quality of diesel fuel should meet European standards, according to which especially high requirements are imposed on the content of organic sulfur compounds in diesel fuel. It is shown that the intensification of the requirements for sulfur content in diesel fuel stimulates the search for new ways to clean it of sulfur compounds and improve the existing technologies of desulfurization processes. This article provides a brief overview of the methods for the desulfurization of diesel fuel. It is shown that one of the important methods for the improvement of the quality of diesel fuel is oxidative desulfurization. Due consideration is given to the various oxidative systems, catalysts and extraction agents used in oxidative desulfurization.
