Process for recovery of hydrocarbons from oil shale

Patent ·
OSTI ID:6900991
; ;
A process for the recovery of hydrocarbonaceous oil from oil shale is disclosed. The process comprises: heating the shale in the presence of a non-combustion supporting, non oil-miscible gas at subcritical conditions of said gas and at a temperature from about 650/sup 0/ F. to about 825/sup 0/ F. to produce a solvent extractable material and to liberate at least a first portion of the hydrocarbon contained therein; and contacting the resulting solvent extractable material with a normally-liquid solvent at subcritical, reflux conditions of said solvent to liberate at least a second portion of the hydrocarbon contained in said solvent extractable material.
