    Abstract: The present disclosure relates to processes for producing hydrocarbon fuels from lignocellulosic biomass. A process may include introducing biomass to a pretreatment system forming a pretreatment effluent and introducing the pretreatment effluent to a hydrolysis system forming a hydrolysate. The hydrolysate may be introduced to a lignin separation system to form a sugar-rich stream and a lignin-rich stream. The sugar-rich stream may be introduced to a purification system comprising at least one toxin converting microorganism or subcellular material to form a purified sugar-rich stream, and the purified sugar-rich stream and one or more sugar converting microorganisms are introduced to a bioreactor configured to produce hydrocarbon fuels. Additionally, the present disclosure also related to systems for production of hydrocarbon fuels including, a pretreatment system, a hydrolysis system, a lignin separation system, a purification system, and at least one bioreactor.

    Abstract: Systems and methods are provided for synthesizing multi-ring disalicylate linkers. The systems and methods can allow for synthesis of disalicylate linkers while using a reduced or minimized amount of solvent (such as down to potentially having no separate solvent) in the reaction environment. The synthesis can be performed by starting with a compound such as 4,4′-biphenol as a starting reagent. The 4,4′-biphenol (and/or other alcohol-substituted biphenyl compound) can then be exposed in a reaction environment to pressurized CO2 in the presence of a base. The temperature and pressure in the reaction environment can be increased to achieve either supercritical conditions for the CO2 (based on a phase diagram for neat CO2) and/or sub-critical conditions that are substantially similar to supercritical conditions. This can allow for conversion of the 4,4′-biphenol (or other alcohol-substituted biphenyl compound) into a multi-ring disalicylate linker.

    Abstract: Venturi-type scrubbers may be utilized in conjunction with removing solids from and quenching a gas-phase reaction product. Methods may comprise: providing a reaction product comprising a hydrocarbon gas and solids; introducing the reaction product into a Venturi-type scrubber; introducing a scrubbing fluid into the Venturi-type scrubber, wherein the scrubbing fluid is at a lower temperature than the reaction product; producing from the Venturi-type scrubber a multi-phase product comprising a scrubbed reaction product and a spent scrubbing fluid, the scrubbed reaction product comprising the hydrocarbon gas and the spent scrubbing fluid comprising the scrubbing fluid and the solids; and separating the hydrocarbon gas from the multi-phase fluid. Systems may comprise a reactor; a Venturi-type scrubber having a first inlet fluidly connected to the reactor and a second inlet configured to receive a scrubbing fluid; and a separation tower configured to receive a multi-phase stream from the Venturi-type scrubber after solids removal.

    Abstract: An electric submersible pump (ESP) system is described herein. The ESP system includes a pump and a motor connected to drive the pump. The pump and motor are disposed to pump fluid into production tubing in a wellbore. The motor produces heat when operating. The wellbore contains wellbore fluids. A seal unit is connected between the motor and the pump. The seal unit contains oil to lubricate the motor. Further, the seal unit receives heat from the motor when the motor is running. The seal unit contains a structure to reduce loss of heat after the motor stops running to reduce an exchange of oil from the seal unit to the wellbore and to reduce an exchange of wellbore fluids from the wellbore to the seal unit.
