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

详细

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°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.
