  • Publication number: 20230286807
    Abstract: There are provided CCUS systems and methods having gas-to-liquid systems and processes, e.g., for processing flare gas to methanol. In these systems an air-breathing engine reformer produces a syngas intermediate that is further converted to methanol in a downstream synthesis step. The CCUS system has a CO2 separator that receives a gas-phase stream and separates this stream into two streams, a CO2-rich stream and a CO2-depleted stream. The CCUS systems may further have a hydrogen separator that receive a gas-phase stream and separates that stream into a hydrogen-rich stream and a hydrogen-depleted stream. The CO2-rich stream can be used for use in EOR, storage or both.

  • Patent number: 10654009
    Abstract: A Venturi draft tube spouted bed and method are disclosed that enables scale-up with small particles and improves heat and mass transfer by increasing material turnover rate. A Venturi-style eductor has been incorporated into the spouted bed draft tube to provide suction at the bottom of the bed to better entrain material and reduce the propensity for dead zones at the bottom of the narrow conical section.

  • Patent number: 10550330
    Abstract: An apparatus and method are described for high-yield fast pyrolysis of biomass feedstock to produce a liquid bio-oil product. A bubbling fluidized bed reactor is provided having an integrated, rapid quench apparatus for minimizing secondary cracking reactions that can otherwise lower the yield of bio-oil. A quench stream is provided inside the reactor to minimize the residence time that the product vapors spend at high temperature where cracking can occur. The quench stream is introduced downstream of the fluidized bed but still internal to the reactor. The fluidized bed medium is constrained to the bottom of the reactor and is not cooled by the quench stream.

  • Patent number: 10352865
    Abstract: A flow cell and method for photometric transmission measurements are disclosed in which a folded optical path provides for co-located, collinear fiber optic read and illumination cables that can be bundled together. Light passes through a fluid sample, is reflected off a pair of right-angle turning mirrors and returns through the fluid for a second pass. A center divider separates fluid passages on the first pass of the light through the fluid and the second pass of the light through the fluid to block any undesired backscattered light from reaching a detector.

  • Patent number: 9166136
    Abstract: Nanostructured elements and a method for fabricating such nanostructured elements with an enhanced power and aerial power density are disclosed. A hierarchical template with ordered and arrayed nanopores is produced on either a mating part or a support material that is pre-shaped so as to be conformable to the mating part. At least one compound can be optionally layered within the nanopores to reduce the diameter thereof. The template is supplied with filling material having selected electrical or thermoelectric properties. Selective removal of the template produces freestanding nanostructure arrays which are then backfilled with thermoelectric material or the like to form a nanostructure array comprised of nanowires supported by the backfilled material on the substrate.
