Abstract
The composition of the structural fragments of resinous and asphaltic molecules in Usinsk heavy oil containing C – S sulfide bonds and of organosulfur compounds in the oily components of this petroleum was studied. The composition of the sulfur–containing fragments of the asphaltenes was studied separately for their low– and high–molecularweight fractions and occluded maltenes. Alkanes, naphthenes, mono and polycyclic aromatic hydrocarbons, dibenzothiophenes, and monobasic aliphatic acids were found in the fragments of the resinous–asphaltic compounds linked by sulfide bridges. The sulfur–containing structures of the oily components are represented by alkyl–substituted thiophenes, benzo, dibenzo, and benzonaphthothiophenes, and bicyclic sulfides. Heat treatment of this petroleum leads to decomposition of the resins and asphaltenes at the sulfide bridges and transition of individual fragments in the distillates, which must be taken into account in upgrading procedures.
