ARCTIC DIESEL FUEL Russian patent published in 2020 - IPC C10L1/08 C10L1/10 C10L1/23 C10L1/188 C10L1/182 C10L1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention discloses arctic diesel fuel based on middle-distillate petroleum fractions, comprising a hydrotreated dewaxed diesel fraction, an anti-wear additive and a hydrocracking kerosene fraction, wherein fuel additionally contains cetane-increasing additive, as hydrotreated dewaxed fraction – hydrotreated dewaxed diesel fraction boiling within 135–370 °C, as hydrocracked kerosene fraction – hydrocracked kerosene fraction boiling in range of 140–250 °C, at the following ratio of components, wt%: hydrotreated dewaxed diesel fraction boiling in range of 135–370 °C – 69.790–94.960; hydrocracked kerosene fraction boiling in range of 140–250 °C – 5.000–30.000; anti-wear additive – 0.010–0.035; cetane-increasing additive – 0.020–0.200.

EFFECT: technical result consists in improvement of low-temperature properties, namely: pour point, turbidity limit temperature, filterability temperature, which provide reliable operation of diesel engines at ambient temperatures minus 65 – minus 70 °C.
