  • Patent number: 11066604
    Abstract: A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.

  • Patent number: 10947466
    Abstract: A method is provided for thermally processing waste to produce steam and generate energy while minimizing air pollutants in a staged thermal reactor. The method includes gasifying the waste to convert the waste to a fuel gas and a substantially carbon free, inert, granulated, sintered mineral ash and reforming the fuel gas auto-thermally to minimize creation of nitrogen oxide when the fuel gas is combusted. The method further includes burning the reformed fuel gas to minimize creation of nitrogen oxide in a flame region of a fuel gas burner and recirculating cooled flue gas to control oxygen content and temperature during the reforming operation and the burning operation. In one example, reforming the fuel gas converts non-molecular nitrogen species into molecular nitrogen in an auto-thermal non-catalytic reformer unit by decomposition reactions promoted by a prevailing reducing gas atmosphere.

The reactor includes a vessel with a loading port and cover, sized to receive biofuel of at least eight by twenty inches. A storage zone provides biofuel via gravity feed only to a plasma zone that oxidizes the biofuel into char and precursor gases. Air nozzles provide air to the plasma zone from a helical air preheater. A char zone receives the precursor gases and char. The precursor gases are substantially converted to effluent gases of hydrogen and carbon monoxide. A grating below the char zone holds the char until it is oxidized to ash. The grating covers the entire bottom of the char zone. The grating is disposed in a substantially fixed and immovable configuration during the operation of the reactor.

  • Patent number: 8545581
    Abstract: Methods for fractional catalytic pyrolysis which allow for conversion of biomass into a slate of desired products without the need for post-pyrolysis separation are described. The methods involve use of a fluid catalytic bed which is maintained at a suitable pyrolysis temperature. Biomass is added to the catalytic bed, preferably while entrained in a non-reactive gas such as nitrogen, causing the biomass to become pyrolyzed and forming the desired products in vapor and gas forms, allowing the desired products to be easily separated.

  • Patent number: 8507567
    Abstract: A system and method for producing Syngas from the CO2 in a gaseous stream, such as an exhaust stream, from a power plant or industrial plant, like a cement kiln, is disclosed. A preferred embodiment includes providing the gaseous stream to pyrolysis reactor along with a carbon source such as coke. The CO2 and carbon are heated to about 1330° C. and at about one atmosphere with reactants such as steam such that a reaction takes place that produces Syngas, carbon dioxide (CO2) and hydrogen (H2). The Syngas is then cleaned and provided to a Fischer-Tropsch synthesis reactor to produce Ethanol or Bio-catalytic synthesis reactor.

  • Patent number: 8377155
    Abstract: The auger gasifier described includes, in its preferred embodiments, a vertically elongated (“oblong”) primary gasifier chamber with an auger that can move up and down, allowing for large amounts of fuel input when necessary. This improvement, in turn, requires and/or is facilitated by provision for simultaneous elevation adjustments of the auger and bed dam to assure that fuel material is processed in degrees from the top downward without sweeping massive amounts of the fluidized bed materials towards the output end of the chamber. Another improvement involves provision for pressurization of the primary gasifier chamber, allowing substantial improvements in the speed of processing materials through the gasifier. Due to issues arising from thermal expansion of the refractory material lining the chamber, provision is made for nozzle and refractory imbedded pipe hole thermal expansion capability.
