Abstract
A composition was studied for polycyclic aromatic hydrocarbons formed in the course of the pyrolysis (160–650 °С) of the resin-asphaltene components of heavy crude oil from the Permian–Carboniferous age deposits of the Usinskoye field (Komi Republic). It was demonstrated that the molecules of resins and asphaltenes inherent in the oil contain the same set of aromatic fragments. Among them there were identified bi- and tricyclic fused aromatic hydrocarbons and (С1-С3 alkyl derivatives, tetra -, penta -, hexacyclic substances and phenyl-substituted compounds (diphenyl-, phenylnaphthalenes, terphenyls, phenylphenanthrenes). Tri- and tetracyclic aromatic hydrocarbons are prevailing, which hydrocarbons should form the basis for the composition of oil fractions produced by means of thermal processing the heavy hydrocarbon feedstock.
