In the paper, the oil separated from the oil-contaminated soil using thermal treatment, and the characteristics of the separated oil were studied. Thermal treatment was carried out under conditions of uniform heating from room temperature to 450 ∘C. The heating rate of the oil spilled on the soil was 15 ∘C per minute. The average duration of the thermal treatment process of the research object was 50 minutes. As the proportion of polluting oil in the soil sample obtained from the neutralization of oil spilled on the soil increases, an increase in the percentage of the separated oil (liquid product) is observed. The liquid products were subjected to physical and chemical analysis. The resulting liquid product had a water content of 7.6%. Its density is 902 kg/m3, flash point is 69 ∘C, and ash content is 0.18 %. It was found that the separated oil is made up of 83.72% oil and 16.28% resin fractions. Asphaltene was not seen during the group composition analysis.
