Abstract:
    A multiple hearth reactor apparatus and process for the thermal treatment of organic carbonaceous materials under controlled pressure and temperature comprising in accordance with one embodiment, a pressure vessel containing a plurality of superimposed annular hearths including a series of upper hearths defining a preheating zone and pointing to the periphery of the reactor with a ceitain angle inclined down, and a series of lower hearths spaced therebelow defining a reaction zone and is spaced in a perpendicularity direction at the lower portion of the container. In accordance with a second embodiment of the apparatus, a separate chamber is employed for preheating of the feed material and the preheated and partially dewatered feed material is thereafter directly charged into the multiple hearth apparatus defining the reaction zone. In operation, the apparatus is adapted to operate at temperatures ranging from about 200 DEG F. up to about 1200 DEG F. or higher at pressures generally ranging from about 300 up to about 3000 psig. Residence times of as little as 1 minute up to about 1 hour or longer can be employed depending upon the nature of the feed material and the desired thermal restructuring.
