Patent
·
OSTI ID:5704826
A system for retorting oil shales known as relatively lean and relatively rich oil shales is described, wherein the shales are mixed to provide an oil shale having a general or average Fischer assay oil content in the range of about 15 to about 36 gal per ton. The mixture thus formed is retorted in a gas-combustion retort under conditions to recover higher yields of oil products than would be obtained when processing each of the different oil shales separately.
