Friedman, R H

This patent describes a method for recovering hydrocarbons from oil shale. The method consists of: (a) grinding the oil shale to a predetermined fineness; (b) exposing the oil shale material to an oxidative environment embodying a free oxygen containing gas at a predetermined temperature for sufficient time to cause oxidative scission of a portion of the kerogen which produces organic fragments removed from the kerogen, the oxidative environment also including a liquid solvent for the organic fragments; (c) separating the solvent and organic fragments from the residual solids; and (d) separating the organic fragments from the solvent.
