A dry thermal processor for recovering hydrocarbons from oil sand solids comprises concentric, radially spaced, horizontal inner and outer tubular members connected for rotation together. The inner member provides a substantially open preheat zone and vaporization zone while the outer member provides, in the annular space between the tubular members, a substantially open combustion zone and heat transfer zone. The ends of the outer member are sealed by stationary feed end and product end structures. Advance means move the oil sand solids from the feed end structure through the preheat and vaporization zones to the product end structure and back through the combustion and heat transfer zones. Rotation of the inner member causes size reduction of the oil sand feed in the preheat zone, and oversize is discharged directly into the annular space at the second end of the preheat zone. Separate means are provided for removing the gases produced in the zones, said means maintaining the gaseous atmospheres in the preheat zone, vaporization zone and annular space substantially segregated from each other.
