This is a method of distilling or retorting oil shale. Coal and/or coke is added to the oil shale to be distilled. The coke is made by subjecting bottoms from the distillation of shale oil to fluid coking. The coke an/or coal supply part of the heat of distillation or retorting. The crushed oil shale and coke mixture is moved upward through a retort by a hydraulic piston, and air or air and steam are passed into the top of the retort for downflow through the retort countercurrent to the upward- moving shale solids. Distilled oil and gases are withdrawn from near the bottom and are passed to a fractionator for further fractionation and treatment. The spent shale is taken off the top of the retort. The temperature of the retorting zone is maintained at between about 2,000 and 2,400$F. About 25 to 50 wt % of coal and between about 15 and 25 wt % of fluid coke particles are added to the shale solids to increase burnable carbon. (3 claims)
