  • 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: 10273422
    Abstract: A bio-reforming reactor receives biomass to generate chemical grade syngas for a coupled downstream train of any of 1) a methanol-synthesis-reactor train, 2) a methanol-to-gasoline reactor train, and 3) a high-temperature Fischer-Tropsch reactor train, that use this syngas derived from the biomass in the bio-reforming reactor. A renewable carbon content of the produced gasoline, jet fuel, and/or diesel derived from the coupled downstream trains of any of 1) the methanol-synthesis-reactor train, 2) the methanol-to-gasoline reactor train, or 3) the high-temperature Fischer-Tropsch reactor train are optimized for recovery of renewable carbon content to produce fuel products with 100% biogenic carbon content and/or fuel products with 50-100% biogenic carbon content.

  • Patent number: 10273415
    Abstract: A bio-reforming reactor receives biomass to generate chemical grade syngas for a coupled downstream train of a low-temperature Fischer-Tropsch reactor train that uses this syngas derived from the biomass in the bio-reforming reactor. A renewable carbon content of the produced gasoline, jet fuel, and/or diesel derived from the coupled downstream train the low-temperature Fischer-Tropsch reactor train are optimized for recovery of renewable carbon content to produce fuel products with 100% biogenic carbon content and/or fuel products with 50-100% biogenic carbon content. The low-temperature Fischer-Tropsch reactor train produces syncrude, transportation fuels such as bio-gasoline or bio-diesel, or a combination thereof.
