Thermooxidative Regeneration of Used Mineral Motor Oils
The physico-chemical properties and group composition of the used mineral motor oils M-10DM and NORMAL 15W40, as well as the fractions obtained as a result of their thermooxidative regeneration have been studied. The results of IR-spectroscopic and X-ray fluorescence analysis of used oils and fractions obtained during thermooxidative regeneration are presented. The changes in the composition and properties of regenerated oils are described.
