Compounding of winter and arctic diesel fuels: Calculated and experimental data

Diesel fuel is the product obtained by hydrotreatment of diesel fractions; it is among the most popular types of motor fuel for surface and water transport. In comparison with gasoline engines, diesel engines are more economical, fire-safe, stable and environmentally friendly. However, their serious drawback is difficult operation at low temperatures. Variants of winter and arctic diesel fuels compounding are considered. It was found that ≤14 % is the admissible amount of summer diesel fraction that can be mixed with winter diesel fraction to decrease the quality margin. The formulation of arctic diesel fuel containing winter diesel fraction, kerosene fraction (no more than 30 %) and pour point depressant- dispersant additive (250-550 ppm) was also obtained.
