Patent number: 8309049Abstract: A molten metal reactor for converting a carbon material and steam into a gas comprising hydrogen, carbon monoxide, and carbon dioxide is disclosed. The reactor includes an interior crucible having a portion contained within an exterior crucible. The interior crucible includes an inlet and an outlet; the outlet leads to the exterior crucible and may comprise a diffuser. The exterior crucible may contain a molten alkaline metal compound. Contained between the exterior crucible and the interior crucible is at least one baffle.Type: GrantFiled: October 19, 2009Date of Patent: November 13, 2012Assignee: Battelle Energy Alliance, LLCInventors: Dennis N. Bingham, Kerry M. Klingler, Terry D. Turner, Bruce M. Wilding

Publication number: 20120282163Abstract: Reactor systems and methods are provided for the catalytic conversion of liquid feedstocks to synthesis gases and other noncondensable gaseous products. The reactor systems include a heat exchange reactor configured to allow the liquid feedstock and gas product to flow concurrently in a downflow direction. The reactor systems and methods are particularly useful for producing hydrogen and light hydrocarbons from biomass-derived oxygenated hydrocarbons using aqueous phase reforming. The generated gases may find used as a fuel source for energy generation via PEM fuel cells, solid-oxide fuel cells, internal combustion engines, or gas turbine gensets, or used in other chemical processes to produce additional products. The gaseous products may also be collected for later use or distribution.Type: ApplicationFiled: July 2, 2012Publication date: November 8, 2012Inventors: Randy D. Cortright, Robert T. Rozmiarek, Charles C. Hornemann

Publication number: 20120269692Abstract: A manufacturing apparatus for producing products results in solid waste and organic waste disposed in an air stream. The organic waste is subject to oxidation by a thermal oxidizer receiving the air stream from the manufacturing apparatus for oxidizing the organic waste. The thermal oxidizer includes a clean air outlet for venting the oxidized air stream to the atmosphere. A gasifier receives solid waste from the manufacturing apparatus for gasifying the solid waste and producing synthetic gas. The synthetic gas is introduced to the thermal oxidizer for providing additional thermal energy to the thermal oxidizer reducing the amount of fossil fuel required to provide thermal energy to the thermal oxidizer that is necessary for oxidizing the organic waste disposed in said air stream.Type: ApplicationFiled: July 3, 2012Publication date: October 25, 2012Applicant: DÜRR SYSTEMS, INCInventors: James Stone, Steven William Blocki
