ARCTIC DIESEL FUEL Russian patent published in 2019 - IPC C10L1/04 C10L1/08 C10G45/58 C10G65/02 

FIELD: chemistry.

SUBSTANCE: invention describes an arctic diesel fuel based on middle distillate petroleum fractions containing, as a base component, an isodewaxed diesel fraction and an antiwear additive added to the base component, while as the base component isodewaxed diesel fraction boiling in the range of 175–360 °C, and the fuel additionally contains a hydrocracking kerosene fraction boiling within 140–240 °C, and a depressant additive, in the following ratio of components,% mass.: isodewaxed diesel fraction boiling in the range of 175–360 °C – 90.000–98.000; hydrocracking kerosene fraction boiling in the range of 140–240 °C – 1.885–9.860; antiwear additive – 0.015–0.040; depressant additive – 0.050–0.100.

EFFECT: technical result consists in obtaining arctic diesel fuel, which has improved low-temperature properties that ensure reliable operation of diesel engines in arctic conditions and the Far North at ambient temperatures below minus 65 °C.
