Patents by Inventor J. Kelly Kindig

J. Kelly Kindig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for the treatment of coal
    Patent number: 7232472
    Abstract: A method and apparatus for the treatment of coal to form a product gas such as methane (CH4), and a high purity carbon product. The method includes contacting a coal-containing feedstock with a treatment gas that includes hydrogen. The coal feedstock can advantageously be a low-grade coal that contains high levels of impurities. The methane product gas can be augmented with hydrogen (H2) gas. Reactants and by-products are advantageously recycled within the process system to enhance the economics of the process.
    Type: Grant

    Date of Patent: June 19, 2007
    Assignee: Alchemix Corporation
    Inventors: J. Kelly Kindig, Robert R. Odle, Thomas E. Weyand, Boyd R. Davis
  • Method for the production of hydrogen gas
    Patent number: 6682714
    Abstract: A method and apparatus for the production of hydrogen gas. The method includes the reduction of steam utilizing a metal species, such as iron or tin, to form pure hydrogen gas. At least two reactors are preferably utilized to continuously form additional metal for the reduction of the steam by reducing a metal oxide. No substantial transport of the non-gaseous reactants (e.g., the metal and metal oxide) is required, thereby simplifying the apparatus and reducing the overall cost of the hydrogen production.

  • Method for the production of ammonia
    Patent number: 6620398
    Abstract: A method for the production of ammonia. The method includes the reduction of steam using a metal species such as iron or tin to form pure hydrogen gas and the reaction of hydrogen gas with nitrogen gas to form ammonia. The nitrogen gas can be formed by extracting the oxygen from air through the oxidation of a metal, yielding nitrogen gas.

  • Method for the production of a methane-containing gas
    Publication number: 20020139049
    Abstract: A method and apparatus for the conversion of a hydrocarbon-bearing feedstock to a valuable product gas such as methane (CH4). The feedstock can advantageously be a low-cost or negative net cost feedstock such as municipal waste or low-grade coal. The method advantageously includes the step of forming large volumes of hydrogen gas and contacting the hydrogen gas with the feedstock to produce methane. The methane can be combusted to produce electricity, such as in a combined cycle generator.
