Meisenburg, E; Keim, K H

This method of processing oil shale or tar sand subjects the oil shale or tar sand to retorting in the presence of hydrogen at a temperature from 380 to 550/sup 0/C and a pressure of 10 to 80 bars, with the exclusion of oxygen, in a retorting zone. The residues of the oil shale or tar sand after the carbonization or distillation step are passed into a combustion zone in which residual coke remaining in the residues is reacted in the presence of oxygen. At least part of the heat produced in the combustion zone is used for heating hydrogen to be introduced into the retorting zone. The method can be conducted in conventional retorting equipment, using known procedures. 20 claims.
