This vigorous action is helping the steady gravitational movement of feed through the vessel. A top inlet for feed and a bottom outlet for residue are provided. Means for preventing air infiltration and means for controlling flow and keeping vessel filled during processing are provided. Any number of outlets for steam, boiling hot water, fluidized and gasified material at various heights of the vessel. Some material require addition of catalysts to bring about a chemical change and reduction in a pyrolitic process.
