Abstract: Methods for completing hydrocarbon wells using variable rate fracturing are provided herein. One method includes positioning a perforation device within a tubular conduit of a downhole tubular, where the downhole tubular extends within a wellbore, and where the wellbore extends within a subsurface region, as well as perforating the downhole tubular using the perforation device to define perforations within the downhole tubular. The method also includes pumping a slurry including fracturing fluid and a lightweight proppant into the tubular conduit according to a variable pumping rate schedule to fracture zones of the subsurface region that are proximate to the perforations, forming corresponding fractures within the subsurface region. The method further includes flowing the slurry into the fractures, via the perforations, to prop the fractures with the lightweight proppant, where the lightweight proppant includes granules formed from a polyolefin, petroleum coke, and/or a polyaromatic hydrocarbon resin.

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: A system and method of extracting elements from an aqueous stream are described herein. The method includes designing a process to extract at least two elements from the aqueous product stream. The at least two elements have different commercial values. The process is optimized to minimize a cost of extracting the at least two elements and to maximize a value of extracting the at least two elements. The method further includes extracting the at least two elements according to the process.

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.

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.
