  • Patent number: 6447437
    Abstract: Industrial combustion facilities are integrated with greenhouse gas-solidifying fertilizer production reactions so that CO2, CO, NOx, and SOx emissions can be converted prior to emission into carbonate-containing fertilizers, mainly NH4HCO3 and/or (NH2)2CO, plus a small fraction of NH4NO3 and (NH4)2SO4. The invention enhances sequestration of CO2 into soil and the earth subsurface, reduces N03− contamination of surface and groundwater, and stimulates photosynthetic fixation of CO2 from the atmosphere. The method for converting CO2, CO, NOx, and SOx emissions into fertilizers includes the step of collecting these materials from the emissions of industrial combustion facilities such as fossil fuel-powered energy sources and transporting the emissions to a reactor. In the reactor, the CO2, CO, N2, SOx, and/or NOx are converted into carbonate-containing fertilizers using H2, CH4, or NH3.

  • Patent number: 6382159
    Abstract: A spark plug for venting excessive engine cylinder pressure may be either pressure or temperature activated. A vent passage is created in a conventional spark plug by drilling an air vent through the housing of a conventional spark plug to a point that experiences cylinder pressures. The air vent is then sealed with a mechanical element of known structural strength and temperature response. Upon the development of excessive engine temperature, cylinder pressure, or both, the sealing element gives way, generating an air passage from the combustion chamber to the atmosphere through which cylinder pressure is vented. By venting excessive pressure, the disastrous effects of detonation, hydrolock, and other deleterious engine conditions may be avoided. Prior to the failure of the seal, the spark plug functions identically to a conventional spark plug.

  • Patent number: 6375716
    Abstract: A gas separation device includes an inner conduit, and a concentric outer conduit. An electrically conductive filter media, preferably a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner conduit and the annular space between the inner conduit and the outer conduit, so as to contact the filter media. The filter media preferentially adsorbs at least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit are preferably electrically conductive whereby the regeneration of the filter media can be electrically stimulated. The invention is particularly useful for the removal of CO2 from the exhaust gases of fossil-fueled power plants.
