  • 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%.
