| 20080299015 | Apparatus and method for top removal of granular material from a fluidized bed deposition reactor - Removal of the product from the top of the reactor enables a decreased disengaging height and provides a passive means of controlling the bed level despite deposition increasing the weight and height of the bed. The savings from reducing the disengaging height allow use of a taller fluidized bed in a shorter overall reactor length and thus provides increased production with reduced reactor cost. The separation of the gas inlet from the product outlet allows the gas inlet area to be cooler than the product outlet. The separation of the product grinding, caused by the inlet gas, from the product outlet reduces the loss of seed in the product and produces a more uniform product. Removing the hot product and the hot gas at the same place allows energy recovery from both in a single step. | 12-04-2008 |

| 20100215551 | Tyer hot gas filter and fluidized bed media cleaner - The gasifier described includes, in its preferred embodiments, a vertically elongated (“oblong”) primary gasifier chamber with an auger and a fluidized bed, allowing for large amounts of fuel input when necessary. The gasifier further includes a gas treatment chamber receiving gases discharged from the gasifier chamber. The fluidized bed in the gasifier chamber as well as the gas treatment chamber contain metallic particles, with these metallic particles circulating in a closed loop between the gasifier chamber and the gas treatment chamber. This system offers numerous benefits. Some or all of said metallic particles can serve as a catalyst in the gasification of the gasifiable materials being processed, including serving as a catalyst for a Fisher Tropsch chemical process in the gasification of said gasifiable materials. In the gas treatment chamber particularly, some or all of said metallic particles serve to clean gases produced in the gasification of said gasifiable materials. The metallic particles can have sizes chosen to provide ate least one of a selected contact area for gases in the gas treatment chamber, and a selected limit on backpressure for an adequate gas stream flow to gas stream cleaning ratio. Also, the metallic particles have a heat retention capacity and this heat retention capacity serves to stabilize the operating temperature of the gasifier. The metallic composition of the metallic particles keeps them from becoming entrained in the gases being discharged from the gasifier chamber, and it is also possible to use the metallic composition of the particles to magnetically separated them from ash issuing from the gasifier chamber (as part of their closed loop circulation). In this circulation, the metallic particles pick up residues in the gas treatment chamber (cleaning the gases passing therethrough), and are cleaned in turn when they pass back through the gasifier chamber. Finally, the overall system allows an oxygen deprived environment and an elevated pressure to be maintained in said gasifier chamber during the closed loop circulation of metallic particles between the gasifier chamber and the gas treatment chamber, promoting maximum efficiency in the gasification process. | 08-26-2010 |
