| 20100275514 | BIOMASS GASIFICATION/PYROLYSIS SYSTEM AND PROCESS - A system and process capable of promoting the energy content of a syngas produced from a biomass material. The system and process entail compacting a loose biomass material and simultaneously introducing the compacted biomass material into an entrance of a reactor tube, and then heating the compacted biomass material within the tube to a temperature at which organic molecules within the biomass material break down to form ash and a fuel gas mixture. The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof. The entrance and exit of the tube, the compaction step, and the removal step cooperate to inhibit ingress of air into the tube by forming a plug of the biomass material at the entrance of the tube and a plug of ash at the exit of the tube. | 11-04-2010 |
