  • Patent number: 10995288
    Abstract: An interconnected set of two or more stages of reactors to form a bio-reforming reactor that generates syngas for a number of different liquid fuel or chemical processes is discussed. A first stage includes a circulating fluidized bed reactor that is configured to cause a chemical devolatilization of the biomass into its reaction products of constituent gases, tars, chars, and other components, which exit through a reactor output from the first stage. A second stage of the bio-reforming reactor has an input configured to receive a stream of some of the reaction products that includes the constituent gases and at least some of the tars as raw syngas, and then chemically reacts the raw syngas within a vessel of the second stage to make the raw syngas from the first stage into a chemical grade syngas by further cracking the tars, excess methane, or both.

  • Patent number: 10443004
    Abstract: Disclosed herein is an integrated plant including, in some embodiments, an interconnected set of two or more stages of reactors forming a bio-reforming reactor configured to generate syngas from wood-containing biomass. A first stage of the bio-reforming reactor is configured to cause a set of chemical reactions in the biomass to produce reaction products of constituent gases, tars, chars, and other components. The first stage includes a fluidized-bed gasifier, a fluidized-bed combustor, and a moving-bed filtration system, each of which includes media inputs and outputs to respectively receive and supply heat-absorbing media to another operation unit for recirculation in a media recirculation loop. The moving-bed filtration system includes a tar pre-reformer configured to capture and reform heavier tars into lighter tars for subsequent processing in one or more fuel-producing reactor trains. Fuel products produced by the one or more reactor trains have a biogenic content of between 50% and 100%.

  • Patent number: 10287508
    Abstract: Multiple stages of reactors form a bio-reforming reactor that generates chemical grade bio-syngas for any of 1) a methanol synthesis reactor, 2) a Methanol-to-Gasoline reactor train, 3) a high temperature Fischer-Tropsch reactor train, and 4) any combination of these three that use the chemical grade bio-syngas derived from biomass fed into the bio-reforming reactor. A tubular chemical reactor of a second stage has inputs configured to receive chemical feedstock from at least two sources, i) the raw syngas from the reactor output of the first stage via a cyclone, and ii) purge gas containing renewable carbon-based gases that are recycled back via a recycle loop as a chemical feedstock from any of 1) the downstream methanol-synthesis-reactor train, 2) the downstream methanol-to-gasoline reactor train, or 3) purge gas from both trains. The plant produces fuel products with solely 100% biogenic carbon content as well as fuel products with 50-100% biogenic carbon content.

  • Patent number: 9771531
    Abstract: An integrated plant to generate chemical grade syngas from a steam biomass reforming in a multiple stage bio reforming reactor for use with either a high temperature or low temperature Fischer-Tropsch synthesis process to produce fuel from biomass is discussed. The first stage has a reactor to cause a chemical devolatilization of a biomass feedstock from the biomass feedstock supply lines into its constituent gases of CO, H2, CO2, CH4, tars, chars, and other components into a raw syngas mixture. A second stage performs further reforming of the raw syngas from the first stage into the chemical grade syngas by further applying heat and pressure to chemically crack at least the tars, reform the CH4, or a combination of both, into their corresponding syngas molecules. The second stage feeds the chemical grade syngas derived from the biomass feedstock to the downstream Fischer-Tropsch train to produce the fuel from the biomass. One or more recycle loops supply tail gas or FT product back into the plant.

  • Patent number: 4274571
    Abstract: A hand-held carrier for a pair of skis and a pair of poles includes a pair of confrontable clamping members hingedly interconnected at their lower ends. The members when in confrontation define a pair of adjacent ski-receiving openings (each for receiving the mid-section of a ski) and a pair of adjacent pole-receiving openings, (each for receiving the mid-section of a pole). The upper ends of the clamping members are releasably interengaged and are latched together by a latching means. A pivotable handle is mounted on one of the clamping members and may be swung as to allow a reduction in the space required by the carrier when loaded onto a car rack, thereby permitting the use of a greater plurality of carriers and supported skis and poles on a particular car.
