  • Method for the production of hydrogen-containing gaseous mixtures
    Patent number: 7335320
    Abstract: A method for the production of a hydrogen-containing gas composition, such as a synthesis gas including hydrogen and carbon monoxide. The molar ratio of hydrogen to carbon monoxide (H2:CO) in the synthesis gas can be well-controlled to yield a ratio that is adequate for the synthesis of useful products such as methane or methanol, without the need to remove carbon oxides from the gas stream to adjust the ratio.

  • METHOD FOR THE GASIFICATION OF HYDROCARBON FEEDSTOCKS
    Publication number: 20070256361
    Abstract: A method for the gasification of a hydrocarbon-bearing feedstock to produce useful co-products such as high-value hydrocarbon fuels, pure H2, electricity, and/or ammonia. The method advantageously gasifies the carbon in the feedstock to carbon monoxide (CO) without producing large quantities of carbon dioxide (CO2). Supplemental hydrogen (H2) is also produced by reacting steam (H2O) with a metal. The method can advantageously produce two separate syngas streams, one that is CO-rich and one that is H2-rich.

  • METHOD FOR THE GASIFICATION OF MOISTURE-CONTAINING HYDROCARBON FEEDSTOCKS
    Publication number: 20070256360
    Abstract: A method for the gasification of a hydrocarbon feedstock that has a high moisture content to produce useful co-products such as high-value hydrocarbon fuels, pure H2, electricity, and/or ammonia. The method advantageously gasifies the carbon in the feedstock to carbon monoxide (CO) without producing large quantities of carbon dioxide (CO2). Supplemental hydrogen (H2) is co-produced by reacting steam (H2O) generated from the moisture in the hydrocarbon feedstock with a molten metal.

  • 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.

  • 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 hydrogen and applications thereof
    Patent number: 6663681
    Abstract: A method for the production of hydrogen gas. The hydrogen gas is formed by steam reduction using a metal/metal oxide couple to remove oxygen from water. Steam is contacted with a molten metal mixture including a first reactive metal such as iron dissolved in a diluent metal such as tin. The reactive metal oxidizes to a metal oxide, forming a hydrogen gas and the metal oxide can then be reduced back to the metal for further production of hydrogen without substantial movement of the metal or metal oxide to a second reactor.

  • 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.
