Cover Story: This article demonstrates the impact of blending diesel fuel with tire pyrolysis oil (TPO) on rheological properties and compliance with legal fuel requirements. Tests were conducted on blends of normative D100 diesel oil with 5, 7, 10, 15, and 20% m/m TPO. Reference measurements were also performed for pure diesel and pure pyrolysis oil. The kinematic viscosity, density, dynamic viscosity, viscosity index, pour point, cloud point, and cold filter plugging point were determined. Densities were measured at 15–100 °C and viscosities at 20, 40, and 100 °C. Approximating models were built for all analyzed parameters and can be used in future studies. Results were compared with limit values specified in selected standards and regulations. Blends with 0–20% TPO met marine distillate fuel standards, while blends with up to 7% TPO complied with Polish diesel fuel regulations. View this paper
