The composition and properties of the oil fractions separated from a mixture of Azerbaijan oils
Y.A. AbdullayevaThe article presents the results of research on selection of the raw materials a mixture of Azeri oil and the study of physical and chemical properties of these oils fractions. As a raw material the oil fractions (380570 C) of a mixture of perspective oil of Azerbaijan (Surakhany, Shirvan, Neft Dashlary) is used. To determine the structural-group composition of oil fractions the dependence among the specific refraction, molecular weight and aniline point oil fractions has been studied. It is shown that the oil fractions of the mixture of oil content of naphthenic hydrocarbons is in the range of 66 75%. They differ with low viscosity index and high pour point. For base oils that meet future requirements (saturates content of 90 %), a combination of selective clearing and destructive hydrogenation processes is recommended.
