Syncoal Production Process

Schematically, this diagram shows the operation of the reactor. Biomass entering the feed hopper is shredded and mixed by paddles mounted on the screw conveyors. The work energy of mixing raises the temperature of the biomass to approximately 550°F, as the material is conveyed along the screw augers. Moisture is removed through the first vent, while gases and oil vapors are removed through the second and third vents. The entire pyrolysis process takes about 90 seconds, after which the hot synthetic coal is deposited into a water-cooled conveying screw to reduce its temperature for safe handling and storage. This process is not incineration. No burning takes place within the reactor, as no air or oxygen is present. The reactor operates at atmospheric pressure, eliminating the need for lock hoppers. The modest reaction temperature limits high temperature corrosion.
