Composition of Oily Components in the Liquid Products of the Supercritical Fluid Extraction of Oil Shale from the Chim-Loptyugskoe Deposit

摘要

The compositions of hydrocarbon and heteroorganic compounds in the oily components of the liquefaction products of oil shale sampled from the Chim-Loptyugskoe deposit have been investigated in benzene under supercritical conditions in temperature ranges up to 200, 200-300, and 300-400 degrees C. It has been found that they consisted of normal and branched-chain alkanes, including unsaturated isoprenoids; alkenes, saturated and unsaturated naphthenes; mono-, bi-, tri-, tetra-, and pentacyclic aromatic hydrocarbons; compounds from the thiophene and benzo-, dibenzo-, and naphthobenzothiophene series; and aliphatic esters and ketones.
