Shale retorting with supplemental combustion fuel

Patent ·
OSTI ID:5863809
;
Disclosed is an oil shale retorting process which is suitable for retorting lean oil shale containing less than 0.13 liters of oil per kilogram of shale. The raw shale is preferably retorted in a staged turbulent bed and the retorted hydrocarbonaceous vapors containing entrained shale fines are withdrawn therefrom. The fines are concentrated in a portion of the liquid product and fed to a combustion with the previously retorted shale to provide the heat required for retorting the raw shale.
