LOW-VISCOSITY MARINE FUEL Russian patent published in 2020 - IPC C10L1/04 C10L1/08 

FIELD: chemistry.

SUBSTANCE: invention describes low-viscous marine fuel containing mixture of weighted middle distillate fractions of primary and secondary oil processing in different ratios: weighted diesel fuel, obtained during atmospheric distillation of oil (222–368 °C), – 0–61 wt%, catalytic cracking light gasoil (175–300 °C) – 30–12 wt%, light gasoil of delayed coking (258–401 °C) – 0–2 wt%, products of vacuum distillation of fuel oil: weighted diesel fuel (264–400 °C) – 70–20 wt%, light vacuum distillate (287–418 °C) – 0–5 wt%, characterized in that it contains 70–88 wt% of weighted fractions with a boiling point of 368–418 °C and low-molecular weight polyethylene in form of 20 wt% solution in diesel summer fuel, weighted fractions to low-molecular weight polyethylene ratio makes 88–70:0.1–0.01 wt%.

EFFECT: production of low-viscosity marine fuel meeting requirements of TU 38_101567-2014, which involves a high percentage of weighted products of primary and secondary oil refining, without application of dispersing and depressant-dispersing additives.
