    Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Some highly porous MOFs lack stability at ambient conditions. MOFs having ambient condition stability may comprise a plurality of metal clusters (M4O clusters, M=a metal), and a plurality of 4-(1H-pyrazol-4-yl)benzoate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. Methods for synthesizing these MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-(1H-pyrazol-4-yl)benzoic acid, and reacting the preformed metal cluster with the 4-(1H-pyrazol-4-yl)benzoic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-(1H-pyrazol-4-yl)benzoate.

    Abstract: Systems and methods are provided for increasing the yield of products generated during co-processing of biomass oil in a fluid catalytic cracking (FCC) system. The systems and methods can allow for increased yield by reducing or minimizing formation of carbon oxides, gas phase products, and/or coke yields during the co-processing. This can be achieved by adding a hydrogen-rich co-feed to the co-processing environment. Examples of hydrogen-rich co-feeds include high hydrogen content vacuum gas oil co-feed, high hydrogen content distillate co-feed, and/or high hydrogen content naphtha co-feed. Additionally or alternately, various types of fractions that contain a sufficient amount of hydrogen donor compounds can be used to reduce or minimize carbon oxide formation.

    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.

    IPC: C07C51/295

    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.
