  • Publication number: 20230407197
    Abstract: A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

  • Publication number: 20230391618
    Abstract: A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

  • Publication number: 20230121665
    Abstract: A feedstock flexible process for converting feedstock into oil and gas includes (i) indirectly heated hydrous devolatilization of volatile feedstock components, (ii) indirectly heated thermochemical conversion of fixed carbon feedstock components, (iii) heal integration and recovery, (iv) vapor and gas pressurization, and (v) vapor and gas clean-up and product recovery. A system and method for feedstock conversion includes a thermochemical reactor integrated with one or more hydrous devolatilization and solids circulation subsystems configured to accept a feedstock mixture, comprised of volatile feedstock components and fixed carbon feedstock components, and continuously produce a volatile reaction product stream therefrom, while simultaneously and continuously capturing, transferring, and converting the fixed carbon feedstock components to syngas.

  • Publication number: 20220154930
    Abstract: A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.
