Residue of distillation, preferably under reduced pressure of oil sand bitumen is thermally treated in a liquid state at a temperature of 350.degree.-450.degree. C. by blowing thereinto an inert heating medium, preferably a superheated steam at a temperature of not lower than the temperature of the residue in a reaction step for 20 to 90 min to crack the residue for converting the residue to a crude synthetic oil, a combustible pitch and a gas, the resultant pitch being utilized to the steps of recovery of oil sand bitumen from oil sand and of distillation as fuel.
