Day, D E

A process of extracting hydrocarbon oil material from oil bearing shale is described which consists of generating hot gases of combustion substantially devoid of oxygen in one chamber, introducing the gases into a second chamber, subjecting the material containing the desired hydrocarbon material within the second chamber to an agitating traveling movement from the entry end to the discharge end of the second chamber and to a heat treatment by contact with the gases to drive off the desired hydrocarbon material. Steam is introduced into the middle of the second chamber during the agitating traveling movement.
