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: 4425219Abstract: The invention relates to an improved method for the production of liquid carbon compounds from coal. According to the invention coal is oxidized at 80.degree. to 300.degree. C. in the presence of the vapors of a C.sub.1-5 aliphatic alcohol, optionally under the introduction of steam, and then the liquid carbon compounds are separated from the resulting product mixture.The process according to the invention can also be performed under atmospheric pressure, 50-80% of the carbon content of the coal converted appear in the liquid product. The liquid product contains the more valuable fraction, boiling below 300.degree. C., as major component.Type: GrantFiled: July 31, 1981Date of Patent: January 10, 1984Assignee: Tatabanyai SzenbanyakInventors: Erik Kroo, Laszlo Kovacs, Istvan Nemes, Katalin Szabo nee Mogyorosi, Geza Szentgyorgyi, Galina Moger nee Eremineva, Andras Nemeth, Dezso Gal, Szilard Riederauer, Janos Szepvolgyi

Patent number: 4368333Abstract: The invention relates to an improved method for the liquid phase oxidation of coal performed with oxygen optionally in the presence of water. According to the invention oxidation is performed in the presence of a cooxidation partner selected from the group of liquid hydrocarbons and oxygen-containing liquid hydrocarbons, and if water is also present, the pH of the homogeneous solution formed from the cooxidation partner and water is maintained at a slightly acidic value.By the method of the invention the formation of carbon dioxide can be suppressed significantly.Type: GrantFiled: July 31, 1981Date of Patent: January 11, 1983Assignee: Tatabanyai SzenbanyakInventors: Laszlo Kovacs, Galina Moger nee Eremineva, Dezso Gal, Peter Hajdu, Julia Lukacs, Erik Kroo, Istvan Nemes, Andras Nemeth, Katalin Szabo nee Mogyorosi, Geza Szentgyorgyi, Szilard Riederauer, Janos Szepvolgyi
