  • Patent number: 9023541
    Abstract: A simple, compact process for cleansing hydrocarbon fuel such as jet fuel is disclosed. This process involves subjecting the fuel to an oxidative desulfurization process in a desulfurization reactor followed by passing the fuel through an adsorption bed. The cleansed desulfurized fuel may then be utilized directly in generation of hydrogen for fuel cell applications.
    Type: Grant

  • Patent number: 8365688
    Abstract: A method and reactor suitable for reformation of fuels at low temperatures is disclosed. The method includes introducing an oxidized porous metal felts with a catalyst powder in a reaction chamber having a heat exchange relationship with a heat-providing chamber, vaporizing a liquid mixture of alcohol and water using an Inconel tubing, and introducing the vaporized liquid into the reaction chamber for producing a methane gas. The fuel reforming reactor includes a heat-providing chamber in a heat exchange relationship with at least one reaction chamber. Each reaction chamber having an aluminum shim lining on at least one interior surface. Each reaction chamber accommodating a catalyst powder and an oxidized porous metal felt. The catalyst powder loaded onto the oxidized porous metal felt to facilitate production of methane gas from alcohol for use with the internal combustion engine.
