FIELD: chemistry.
SUBSTANCE: invention describes high-viscosity marine fuel including the use of distillate of the secondary cracking processes with boiling points of 350-500°C, characterized in that, in addition, a visbreaking residue (VR) is used as a component, which is compounded with a distillate of the secondary cracking processes (DSCP), in a weight ratio: visbreaking residue of 20-60; distillate of the secondary cracking processes - 40-80 and a depressant-dispersant additive is added into the produced marine fuel, which is a mixture of polymethylmethacrylate with its diene, ethylene, propylene and polypropanol copolymers, in an amount of 0.0125 to 0.5000 wt %.
EFFECT: producing a high-viscosity marine fuel with improved low-temperature properties, in particular, with the lowest pour point.
