A dry thermal processor for recovering vaporized substances from particulate host solids is described, comprising: inner and outer, radially spaced apart, interconnected tubular members which rotate together in response to a drive applied to the outer tubular member; said inner tubular member comprising a plurality of substantially parallel spaced apart preheat tubes each having first and second ends, a vaporization tube having first and second ends, and tubular junction means whereby sequential preheat and reaction zones are provided by the inner tubular member; means for passing solids from the preheat zone to the reaction zone and restricting gas movement there between; said tubular members forming an annular space with first and second ends between them to provide sequential open combustion and heat transfer zones proximate the reaction zone and preheat zone, respectively; means for closing the second end of the vaporization tube; means for passing coked solids from the second end of the reaction zone, through said vaporization tube closing means, into the combustion zone and restricting gas movement between said zones; means for recycling hot solids from the second end of the combustion zone into the first end of the reaction zone and restricting gas movement there between; means for drawing gases separately from the preheat zone, the reaction zone, and the annular space; means extending into the combustion zone for injecting oxidizing gas and for supplying supplemental heat there into; said outer tubular member carrying internal lifters in the combustion zone for lifting and dropping coked solids passing therethrough to assist combustion; stationary end frames associated with the tubular members and closing the first and second ends of the annular space; means for feeding feedstock into the preheat tubes; means for removing cooled solids from the annular space through the first end frame; and means for rotating the outer tubular member.
