Structural Characteristics of the Resin-Asphaltene Components of the Organic Matter of Oil Shale from the Dmitrievskoe Deposit and the Liquid Products of Its Conversion in Supercritical Benzene

The averaged molecules of asphaltenes and resins of the organic matter of oil shale from the Dmitrievskoe deposit and the liquid products of its conversion in a flow of supercritical benzene were described using structural group analysis based on the joint use of information on the elemental composition, average molecular weights, and H-1 NMR-spectrometric data and the results of X-ray diffraction analysis. The results obtained made it possible to expand the understanding of the macromolecular structure of the resin-asphaltene components of oil shale formations and to reveal similarities and differences in their structural organization.
