  • Patent number: 9675922
    Abstract: A device and method for producing a reformate fuel from a hydrocarbon gas source. The invention enables the conversion of a dilute hydrocarbon gas into a more easily consumable reformate fuel. Gases having low concentrations of hydrocarbons are concentrated using a concentrator into a gaseous or liquid concentrated VOC fuel. The concentrated VOC fuel is then converted into a reformate using a reformer. The reformate is more easily consumed by an energy conversion device such as a combustion engine, fuel cell, sterling engine or similar device that converts chemical energy into kinetic or electrical energy. The reformer enables complex hydrocarbon fuels that are not normally suitable for use in an energy conversion device to be converted into a reformate. The reformate may be directly supplied into the energy conversion device.

  • Patent number: 7094388
    Abstract: The exhaust of a vehicle paint spray booth is fed through an adsorption medium, such as activated carbon, to remove volatile organic compounds by adsorption. When the adsorbent becomes saturated, it is purged by electric heaters, and the desorbed volatile organic compounds are directed to the fuel processor of a stationary fuel cell. The volatile organic compounds are broken down into oxides of carbon and hydrogen gas in the fuel processor, the hydrogen is fed to the fuel cell, and the oxides of carbon are vented to the atmosphere with excess air. The fuel cell combines the hydrogen with oxygen from air, and releases air, water vapor and electrical power.
