Thermal transformations of resin-asphaltene components of oil residue in the presence of sunflower oil

Thermal transformations of resins and asphaltenes of the oil residue at a cracking temperature of 435°C in the presence of sunflower oil are investigated. The object of the study was the residue of atmospheric-vacuum distillation of a heavy oil from the Zuunbayan oilfield. The structural group parameters of the molecules of resins and asphaltenes of initial fuel oil and thermolysis products are determined on the basis of data of elemental composition, molecular mass, and 1H NMR spectra.
