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

FIELD: chemistry.

SUBSTANCE: invention discloses marine low-viscosity fuel, which can be used as fuel for low-speed engines, containing a mixture of such fractions of primary treatment of oil, as weighted diesel fuel from the top of vacuum distillation column of fuel oil. GC-3 (fraction 224–389 °C) (UDT VP GK-3); weighted diesel fuel from atmospheric distillation column. ELOU + AVT-6 (fraction 222–348 °C) (UDTAP ELOU + AVT-6); light vacuum distillate from top of vacuum distillation column of wide oil fraction of mouth. ELOU + AVT-6 (fraction 287–418 °C) (LVD ELOU + AVT-6); weighted diesel fuel from top of fuel oil vacuum distillation column. ELOU + AVT-6 (fraction 264–400 °C) (UDT VP ELOU + AVT-6) and heavy diesel fractions of secondary origin, as a still residue obtained during atmospheric-vacuum distillation of hydrogenation units of hydrogenation of heavy middle distillate fractions of primary and secondary processing oil (fraction 232–387 °C) (SR); easy catalytic cracking gasoil. GK-3 (fraction 198–331 °C) (LGKK) and depressor-dispersant additive in amount of 0.04 wt. %, characterized by that it additionally contains antioxidant additive Kerobit TP26P in amount of 0.03 wt. %.

EFFECT: technical result is providing stability of low-viscosity ship during storage.
