fuel oil

The effect of fuel oil on the environmental parameters of diesel fuel and the possibility of using it to reduce environmental pollution from road transport were investigated. It was established that fuel oil additives have a positive effect on the main parameters that can affect the ecology of diesel fuels and ensure their support according to Euro standards. The optimal concentrations of fuel oil additives for improving the environmental parameters of diesel fuel, such as density, viscosity, cetane index, boiling points of 10% and 50% fractions, were determined.

The process of paraffin formation has been considered, including the peculiarities of the paraffin structure as a result of phase transitions with a decreasing temperature. Mathematical models for thermodynamic and kinetic calculations of the "solid-liquid" system phase equilibrium have been developed. To shift the "fuel oil-paraffin" balance towards the liquid, it is necessary to reduce the activity ratio of solid and liquid phases by introducing into the system a substance with a lower solubility parameter.
