ABSTRACT:
A pyrolysis unit in which feed materials containing cellulose or oil are subjected to destructive heating to drive off gases and liquid vapors while leaving solid residue in the form of nearly pure carbon. The feed materials are conveyed in succession through horizontal reaction cylinders located at different elevations. Heat is applied by the burning of solid fuel in a firebox of the unit and also by injecting into each cylinder the process gas driven off in the immediately succeeding cylinder. A feeder which delivers both the fuel and feed materials includes drying zones in which combustion gases are directed through the fuel and feed materials to preheat and dry them and to filter the combustion gases.
