ABSTRACT:
A multiple hearth apparatus and process for the thermal treatment of organic carbonaceous materials under controlled pressure and temperature comprising a pressure vessel containing a plurality of superimposed annular hearths including hearths in a reaction zone of the apparatus which are formed with a foraminous upper surface disposed in communication with a plenum for injecting a heated fluid into heat exchange contact with the feed material disposed thereon. The injected heating fluid or gas in further combination with the volatile gases evolved during the thermal restructuring reaction pass countercurrently relative to the travel of the feed material to effect a preheating thereof to a moderate temperature in a preheating zone of the apparatus. Preferably, at least a portion of the volatile gases from the apparatus are treated to remove condensible portions thereof and are reheated and pressurized for recycle to the apparatus. In operation, the apparatus is adapted to operate at temperatures ranging from about 200.degree. F. up to about 1200.degree. F. at pressures generally ranging from about 300 up to about 3000 psig. Resident times of as little as one minute up to about 1 hour can be employed which will vary depending upon the type of feed material and the desired upgraded solid product.
