| Abstract: | A change in the group composition of the liquid products of the supercritical fluid extraction of combustible shale under nonisothermal conditions at various solvent pressures was found. As the solvent pressure was increased, the yield of liquid products was found to increase mainly at the expense of high-molecular-weight substances (preasphaltenes and asphaltenes). |
