Composition of the liquid products of the supercritical fluid extraction of oil shale from the Chim-Loptyugskoe deposit

摘要

Data on the liquid product composition of the thermal degradation of the organic matter of an oil shale sample from the Chim-Loptyugskoe deposit in benzene under supercritical conditions in temperature ranges to 200, 200-300, and 300-400A degrees C were acquired with the use of a set of analytical methods. It was found that the concentration of tar-asphaltene substances in the pyrolyzates decreased with temperature; in the structure of these substances, the fraction of aromatic fragments increased and the fraction of aliphatic fragments decreased. The fraction of polar compounds in the composition of oil components decreased.
