ABSTRACT:
In the apparatus, concentric, radially spaced tubes are secured to each other and rotated about a common horizontal long axis. Selectively placed and configured lift elements repeatedly lift and drop feed material in the two tubes. Advance elements cause the feed material introduced into the feed end of the structure to advance through the inner tube where it is progressively heated, dehydrated and its hydrocarbon content is largely vaporized. The hydrocarbon vapors are removed from the opposite product end of the structure. The remaining solid material falls from the end of the inner tube into a combustion zone in the outer tube. Oxygen supplying means are provided for causing the carbon coatings on the particles in the combustion zone to burn to produce heat employed in the processing of the feed material. The solid particles in the outer tube are moved back toward the feed end by advancing elements. Recycle fixtures divert a portion of the hot, solid material which has had its carbon coating burned off back into the inner tube to be mixed with the incoming feed material. Means are described for processing the hydrocarbon vapors removed from the inner tube and for cleaning combustion gases and vapors removed from the feed end of both tubes.
