Processes including the production of non-congealing shale oil from oil shales
Patent
·
OSTI ID:6528704
Oil shale is partially dehydrated prior to retorting. Both the dehydrating and retorting steps are carried out by heat treatment in rotating horizontal cylindrical vessels heated by indirect heat exchange with hot gas. The vapors withdrawn from the retorting step are fractionated to yield products including a heavy conversion oil.
