METHOD OF PRODUCING DIESEL FUEL Russian patent published in 2024 - IPC C10G65/14 C10L1/00 

FIELD: oil industry.

SUBSTANCE: invention relates to processes of oil refining industry, in particular, to methods of producing diesel fuel. Invention relates to a method of producing diesel fuel, including distillation of oil with extraction of fuel oil and its further vacuum fractionation, extraction of straight-run fractions of heavy and light diesel fuel, hydrotreatment of straight-run fraction of light diesel fuel and straight-run fraction of heavy diesel fuel at high hydrogen pressure in the presence of catalysts based on aluminium, cobalt, nickel and molybdenum, mixing the fraction of hydrotreated light diesel fuel and hydrotreated heavy fuel, so that 95% of the volume boils out at no higher than 360 °C, introduction of additives. Vacuum fractionation of fuel oil is carried out with separation of fraction with boiling point 360-390 °C, with introduction of separated fraction into straight-run fraction of heavy diesel fuel before its hydrotreatment.

EFFECT: efficient use of vacuum distillate fraction with boiling point of 360-390 °C and increase in output of commercial diesel fuel by 11-18%.
