Abstract
An apparatus and method for performing a continuous thermal treatment of organic carbonaceous materials under controlled pressure in which the feed material is introduced into the system in the form of a slurry, and the level of liquid is maintained at a preselected operating level, serving as a gas-tight seal. The feed material is conveyed upwardly of the liquid operating level and is thereafter introduced into a reaction chamber in which it is heated to within a controlled elevated temperature range under controlled pressure in a manner to effect vaporization of at least a portion of the volatile substances therein, forming a gaseous phase composed of condensible and noncondensible vapors. The gaseous phase is withdrawn from the reaction chamber in a direction countercurrent to the travel of the feed material and in heat exchange relationship therewith, effecting condensation of the condensible phase and transport of the noncondensible phase, and is extracted from the system through a discharge port disposed above the liquid operating level. The thermally reacted product is cooled and transferred from the reaction chamber into a receiving chamber from which it is extracted contin…
