  • Patent number: 10370198
    Abstract: Methods and systems for transferring feed materials between zones having substantially different pressures, where the transfer can be continuous or semi-continuous. The methods and systems include a plurality of lock hoppers to receive feed material from a low pressure zone and pressurize it with fluid to a pressure of a high pressure zone. The pressurized material can be discharged to a circulation loop, which carries the pressurized material to one or more receiving unit(s) of a pressurized system. At least some feed material remains in the receiving unit(s) and at least a portion of the fluid exits to become part of the circulation loop. After discharge, the lock hoppers can be depressurized so the next pressurization cycle can begin with additional feed material. The lock hoppers can be operated in a time-staggered manner to provide continuous or semi-continuous transfer of material.

  • Patent number: 10221362
    Abstract: A process for the production of a higher hydrocarbon useful as gasoline component from solid biomass is provided. The process provides for longer ZSM-5 condensation catalyst life by contacting the stable oxygenated hydrocarbon intermediate containing diols produced from digestion and hydrodoxygenation of the solid biomass to an amorphous silica alumina catalyst to reduce the diols content, and optionally removing water, prior to contacting with the ZSM-5 condensation catalyst.

  • Patent number: 10167243
    Abstract: An improved process for the production of a higher hydrocarbon from solid biomass is provided. Solid biomass that has been digested and hydrodeoxygenated in a liquid digestive solvent in the presence of a hydrothermal hydrocatalytic catalyst is separated to an organic rich phase and an aqueous rich phase containing diols. At least a portion of the aqueous rich phase is contacted with an acidic amorphous silica alumina catalyst producing monooxygenate-containing stream comprising water, organic monooxygenates, and unsaturated aliphatic hydrocarbons. At least a portion of the monooxygenate-containing stream is contacted with a solid acid condensation catalyst to produce a higher hydrocarbons stream. At least a portion of the organic rich phase is also contacted with a solid acid condensation catalyst to produce a higher hydrocarbons stream.

  • Patent number: 10106746
    Abstract: Systems and methods involving hydrocatalytic reactions that use molecular hydrogen obtained from a biogas generated from at least a portion of the hydrocatalytic reaction product. Hydrocatalytic reactions can require significant quantities of molecular hydrogen, particularly if the molecular hydrogen is being introduced under dynamic flow conditions. The present disclosure provides systems and methods that can allow for reducing the carbon footprint of the fuels formed from the hydrocatalytic reaction because at least a portion of the hydrogen used in the hydrocatalytic reaction has low carbon footprint. A fuel with low carbon footprint can qualify for certain governmental status that provides certain benefits.
