Patent number: 7794862Abstract: The method for generating a hydrogen-rich stream from hydrocarbon fuels, ultimately to produce hydrogen gas, involves the following two steps performed in a cyclic fashion: (1) pyrolysis of the hydrocarbon fuel to obtain a carbon-rich fraction and a hydrogen-rich fraction; and (2) oxidation of the carbon-rich fraction, or a portion of it, for heat generation. The method involves the following optional steps: (3) steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; (4) water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and (5) steam reforming of light hydrocarbons that may be produced in step (1) to produce more hydrogen and carbon monoxide.Type: GrantFiled: March 20, 2008Date of Patent: September 14, 2010Assignee: Advanced Fuel Research, Inc.Inventors: Marek A. Wojtowicz, Michael A. Serio, Erik Kroo, Eric M. Suuberg

Patent number: 7241323Abstract: Solid waste resource recovery in space is effected by pyrolysis processing, to produce light gases as the main products (CH4, H2, CO2, CO, H2O, NH3) and a reactive carbon-rich char as the main byproduct. Significant amounts of liquid products are formed under less severe pyrolysis conditions, and are cracked almost completely to gases as the temperature is raised. A primary pyrolysis model for the composite mixture is based on an existing model for whole biomass materials, and an artificial neural network models the changes in gas composition with the severity of pyrolysis conditions.Type: GrantFiled: January 10, 2006Date of Patent: July 10, 2007Assignee: Advanced Fuel Research, Inc.Inventors: Michael A.

Patent number: 6890507Abstract: Carbon-containing fly ash has been treated with optimum amounts of ozone. There is homogenous treatment of the fly ash with ozone and over saturation with ozone is avoided. In a further embodiment of the invention carbon, from various sources is oxygenated to be incorporated into concrete. The preferred oxygenating agent is ozone.Type: GrantFiled: September 17, 2002Date of Patent: May 10, 2005Assignee: Brown University Research FoundationInventors: Xu Chen, Yuming Gao, Robert H. Hurt, Eric M. Suuberg, Arun K. Mehta

Patent number: 6746654Abstract: A method for removing ammonia from fly ash employs water mist (a water fog) or a flowing warm humid air stream to rid the fly ash of ammonia. Ozone alone or with other co-oxidants such as hydrogen peroxide are also used to rid fly ash of ammonia.Type: GrantFiled: December 4, 2002Date of Patent: June 8, 2004Assignee: Brown University Research FoundationInventors: Arun K.

Patent number: 5988395Abstract: Disclosed herein is a method and system for sorting recycled solid waste materials, such as plastics, by a liquid-fluidized bed classifier (LFBC) technique. The application of a LFBC to the separation of plastics, and in particular plastic particles, is shown to be advantageous for a number of reasons. Firstly, the primary fluidization medium, i.e., water, is present in large quantities during conventional chopping, washing, and flotation operations that are performed during plastics recycling operations. Secondly, the natural density distribution of the major types of recycled plastics favors segregation by density in water, i.e., the "lighter-than-water" polyolefins, polypropylene (PP) and polyethylene (PE) from the "heavier-than-water" polystyrene (PS) PVC and PET plastics. The latter types of plastics have been found to separate spatially in an upflow LFBC, while the "lighter-than-water" plastics can be collected at the top of the column, thereby combining flotation and classification in a single step.Type: GrantFiled: April 24, 1995Date of Patent: November 23, 1999Inventors: Joseph M.
