Abstract
The fluidized solids technique has been applied successfully to the flash distillation of oil from Alberta bituminous sand on a laboratory scale. At 500 °C. a 76% oil recovery was obtained. The remaining 24% produced approximately equal weights of coke and gaseous compounds. At temperatures below 460 °C. trouble was experienced in maintaining a fluidized bed because of the slow rate of distillation. As temperatures were increased above 500 °C. the yield of oil decreased, with a corresponding increase in gas formation.
