Abstract: Methods of stimulating a hydrocarbon well are disclosed herein. The hydrocarbon well includes a wellbore that extends within a subterranean formation and a tubular that extends within the wellbore and defines a tubular conduit. The methods include retaining a sealing structure within the tubular conduit and, during the retaining, stimulating a zone of the subterranean formation. Subsequent to the stimulating, the methods include fluidly isolating the zone of the subterranean formation from the uphole region by at least partially sealing the plurality of perforations. Subsequent to the fluidly isolating, the methods include moving the sealing structure in a downhole direction within the tubular conduit. The methods also include repeating the retaining, the stimulating, the fluidly isolating, and the moving a plurality of times to stimulate a plurality of corresponding zones of the subterranean formation.

Abstract: Amine-functionalized organosilica materials are provided that have improved stability when exposed to oxidizing/oxygen-containing environments during cycling of temperature, such as the cycling of temperature that occurs when using a material as a sorbent during successive adsorption/desorption cycles. Methods of performing CO2 sorption/desorption with improved stability of the organosilica sorbent material are also provided. The improved stability is achieved in part by using amine-functionalized organosilica materials where the amine-functionalization is provided by functional groups that include primary amines but do not include secondary amines. Still further improvements in stability can be achieved when the functionalization is provided by a functional group that includes a primary amine while also not having any hydrogens on a carbon atom that is in the beta position relative to the primary amine.

Abstract: Systems and methods are provided for using a two-step process to capture CO2 from a process flue gas in an aqueous solution followed by conversion of the captured CO2 into metal carbonates for storage, transport, or other potential uses. In the first processing step, CO2 is removed from a process flue gas by contacting the process flue gas with an aqueous solution at a sufficiently high pH to enhance capture of the CO2 while reducing or minimizing other impacts on the vessel where capture is performed. The CO2-enriched aqueous solution is then passed into a second zone, such as a second vessel, for contact with a metal reagent, such as a metal oxide, metal sulfide, metal hydroxide, and/or metal silicate.

Abstract: The present disclosure relates to polyethylene compositions, articles (e.g., films) including such polyethylene compositions, and methods of making polyethylene compositions and articles (e.g., films) thereof. The polyethylene composition comprises 80 wt % or greater ethylene-derived units; has density within the range from 0.940 to 0.975 g/cm3; a melt index (MI) of 0.1 to 3.0 g/10 min (such as 0.5 g/10 min to 2.5 g/10 min); a high load melt index (HLMI) within the range from 60 g/10 min to 150 g/10 min; a melt index ratio (MIR, defined as HILMI/MI) greater than 50; and has a crossover frequency (COF) according to the following relationship: COF>−0.00015*(Mw)+80 (where COF is in rad/s and Mw is weight-average molecular weight in g/mol).

Abstract: The present disclosure provides a process that includes providing bitumen; performing thermal upgrading on the bitumen to form mildly upgraded bitumen; distilling the mildly upgraded bitumen to form streams of naphtha; distillates and/or gas oils; and residue; combining the naphtha and residue to form a naphtha/residue stream, which causes deasphalting to occur, and forming streams of deasphalted oil and high-carbon pitch comprising asphaltenes; and adding the distillates and/or gas oils to the deasphalted oil to form partially upgraded bitumen.

Abstract: A process for preparing a cement composition comprising an isoolefin-alkylstyrene copolymer and substantially free of an alkylstyrene monomer is described herein. The process comprises reacting the isoolefin monomer with at least a portion of the alkylstyrene monomer in a diluent to form an isoolefin-alkylstyrene copolymer, replacing the diluent with a solvent, reacting a halogenic scavenger with the unreacted alkylstyrene monomer in an absence of a free radical initiator in order to form a halogenic alkylstyrene compound without altering the isoolefin-alkylstyrene copolymer, and removing the halogenic alkylstyrene compound from the slurry to form the cement composition substantially free of the alkylstyrene monomer. Also disclosed herein is a composition comprising an isoolefin-alkylstyrene copolymer and an alkylstyrene monomer comprising a concentration less than about 20 ppm.

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. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Abstract: Processes for making olefin copolymers, particularly ethylene-based copolymers. A process for making an olefin copolymer can include introducing an olefin monomer, at least one other olefin comonomer, and a single type of catalyst system to a tubular reactor to produce an olefin copolymer containing: a) an absolute comonomer distribution (CD) slope 90 of about 2.0 to about 30.0, an absolute CD slope 75 of about 2.0 to about 30.0, an absolute CD slope 50 of about 2.0 to about 30.0, or an absolute CD slope 25 of about 2.0 to about 30.0; b) a first long chain branching index (g′(Mz)) of about 0.30 to about 1.0; and c) a second long chain branching index (g′(Mz+1)) of about 0.30 to about 1.0. The tubular reactor can include one or more plug flow components, one or more spiral heat exchangers, and/or a recycle pump.

Abstract: A method and system for direct quantification of the concentration of biomolecules in algal biomass. The biomolecules include lipids, proteins, and carbohydrates. An algae slurry is cultivated within a cultivation vessel, and algal biomass is harvested therefrom. A portion of biomass is analyzed using solvent-lipid analysis to extract lipids and nuclear magnetic resonance spectroscopy is used to quantify the biomolecular concentration of the biomass.
