2020-11-25 · Before retorting, the oil shale is crushed into fine particles with a size of less than 25 mm (1.0”) in diameter. The crushed oil shale is dried in the fluidized bed drier (aero fountain drier) by contact with hot gases. After drying and pre-heating to 135 °C , oil shale particles are separated from gases by cyclonic separation.

Abstract. Oil shale can be thermally distilled at a shale rate above 300 lb/hr/sq ft by a method which includes passing crushed oil shale material downward through a gas combustion retort as a relatively dense moving mass of material through a shale preheat zone, a retorting zone, a combustion zone, and shale cooling zone.

2008-4-1 · Oil shale distillates (products of retorting) typically favor the production of middle-distillates (diesel and kerosene), and have higher concentrations of nitrogen than crude oil. To produce light-distillates (such as gasoline) additional processing, such as hydrocracking, is required to break down the larger hydrocarbons.
