The integration of oxidative desulfurization and hydrotreating allows, involving heavy oil fractions and fractions of secondary processes, obtaining motor fuels that comply with the regulations of the Russian Federation. For fuel samples with different sulfur content, we performed experiments to determine sulfur content, hydrocarbon-type, sulfur- and nitrogen-containing composition of compounds. The research shows that preliminary oxidative desulfurization decreases the content of heteroatomic and polyaromatic compounds. Thus, it is reasonable to combine these processes for fractions with an initial sulfur content of more than 0.200 mass%.
