Evaluation of the Feasibility of a Simultaneous Change in the Fractional Composition and the Involvement of Depressant Additives to Obtain Low-Freezing Diesel Fuels.

In this paper, the characteristics of a straight-run diesel fuel sample, narrow diesel fractions, and their blends with a depressant additive are tested and analyzed. The efficiency of the depressant additive action on the low-temperature properties of narrow diesel fractions is evaluated. It is shown that the depressant additive is most effective on the pour point of the heavy diesel fraction (300-360 °C) and cold filter plugging point of the light diesel fraction (180-240 °C).
