Abstract
This study aimed to synthesize a pour-point depressant for diesel fuel using intermediate products and waste materials from the Angarsk Petrochemical Company and the Angarsk Polymer Plant (Angarsk, Russia). The work provides a brief review of the quality requirements for diesel fuel and demonstrates the quality of base diesel fuels produced by Angarsk Petrochemical Company. The study characterizes the depressant-dispersant additives used in the production of commercial diesel fuels, along with the research methods and objects. The mechanism of interaction between styrene and low-molecular-weight polyethylene during radical copolymerization was established. The key patterns of the styrene and low-molecular-weight polyethylene copolymerization process were identified, and the structure of the resulting copolymer was determined. The depressor effect of the additives was assessed in base diesel fuels with different low-temperature characteristics. The relationship between the low-temperature characteristics of the base diesel fuels and the additive concentration was illustrated. The use of the novel pour-point depressants at concentrations of 0.1–1.0 wt% was found to reduce the pour point to -42 °C, thereby achieving a depression of the cold filter plugging point to 21 °C. The use of the developed pour-point depressant facilitates the production of value-added interseasonal diesel grades D and E from summer diesel grade A base fuels without altering the fractional composition. In addition, the value-added winter diesel classes 0, 1, and 2 can be obtained from winter diesel grade D base fuels.
