Abrégé
High molecular weight elastomers, such as ethylene-propylene-diene monomer (EPDM) polymers, are conventionally formulated with a post-polymerization oil extension to mitigate their high Mooney viscosity. Post-polymerization oil extension adds to processing costs and precludes use of polymerization facilities lacking oil extension capabilities. A low molecular weight polymer may be co-produced with a high molecular weight elastomer containing the same monomers, where the low molecular weight polymer may function in place of conventional oil extension. Polymerization methods may form a polyolefin blend comprising first and second polyolefins having a bimodal molecular weight distribution.

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.

The method includes determining observation property data corresponding to the treatment stages that have been assigned to the fracture hits and iteratively assigning, based on such data, each unassigned fracture hit to one of the corresponding likely originating treatment stages.

Systems and methods are provided for performing amine capture on a heated flue gas using multiple rotating packed beds. By integrating a series of rotating packed beds to perform cooling of the flue gas, removal of CO2 from the flue gas by contact with an aqueous amine, and washing of the gaseous effluent from CO2 removal step to remove any entrained amine, the equipment footprint and overall equipment volume required for CO2 capture can be significantly reduced. The integration of cooling, CO2 removal, and washing can be integrated into a series of packed beds in part by using different packing materials in the various packed beds.

In various aspects, molten carbonate fuel cell configurations are provided that include a reforming catalyst and alkali traps integrated with one or more structures within the anode gas-collection volume. The purpose of the reforming catalyst is to reform methane (or some other reformable fuel) into hydrogen. In operation, alkali metals may migrate from the fuel cell electrolyte into the anode. Unless trapped, the alkali metals may deactivate the reforming catalyst. The alkali trap prolongs the operating life of reforming catalyst within the anode volume by capturing some portion of the alkali metal in the anode gas-collection volume. This reduces an amount of alkali metal that interacts with the reforming catalyst in the anode gas-collection volume. The prolonged life of the reforming catalyst prevents a decrease in catalyst activity.

In various aspects, systems and methods are provided for operating an oxygen-fired catalyst regenerator with flue gas recycle and CO2 capture. An oxygen-fired catalyst regenerator contrasts with an air-fired regenerator. The oxygen-fired catalyst regenerator substantially reduces nitrogen within the system, which facilitates CO2 capture by reducing the energy required to capture CO2. In various aspects, a first portion of the regenerator flue gas is passed to a CO2 capture system and a second portion is recycled to the regenerator. Before the flue gas is recycled or diverted to the CO2 capture, it is passed to various processes that remove and/or reduce SOx, NOx, particulate, and water content. In various aspects, a portion of the treated flue gas may be combined with substantially pure O2 and recycled to the regenerator.

Amorphous silica-alumina support materials are provided that can serve as supports for polyamines. The silica-alumina support materials have a combination of properties that unexpectedly allow supported polyamines to retain an increased or maximized amount of CO2 sorption capacity after incorporation of substantial amounts of the polyamine on the support material. This combination of properties can include having a high pore volume, a high ratio of mesopore volume to micropore volume, and a sufficiently high acidity. The ability to allow supported amine sorbents to retain additional CO2 sorption capacity is unexpected. Additionally, the relationship between having sufficiently high acidity and providing improved sorption capacity for a supported amine material is unexpected.

Methods are provided for upgrading of pyrolysis carbon in order to allow for conversion of the pyrolysis carbon into higher value products. Instead of attempting to convert methane into a high value carbon product (such as carbon nanotubes) and H2 in a single reaction step, pyrolysis conditions can be used to form H2 and pyrolysis carbon. The pyrolysis carbon can then be treated in order to convert the pyrolysis carbon (H to C atomic ratio of less than 0.20) into a product with a higher hydrogen content (H to C atomic ratio of 0.25-0.9 or 2.0-7.0 wt % H). The treatment can correspond to exposing the pyrolysis carbon with hydrogen in the presence of a catalyst, exposing the pyrolysis carbon to conditions for alkylation, or a sequential combination thereof. This can convert the pyrolysis carbon into heavy hydrocarbon products that are resin-like solids at room temperature.

Pitch particles may be produced by a grinding process, in which pitch fines may be recovered and recycled to a grinding apparatus as a pitch melt. Such methods may comprise: providing a petroleum pitch having a first softening temperature; grinding the petroleum pitch in a grinding apparatus below the first softening temperature to produce a plurality of pitch particles and a plurality of pitch fines; separating the pitch particles from the pitch fines; heating the pitch fines at a temperature above the first softening temperature to produce a pitch melt; and combining the pitch melt with the petroleum pitch in the grinding apparatus. The pitch melt hardens in the grinding apparatus and is reground. The pitch particles may be further stabilized by heating at a treatment temperature below the first softening temperature in an environment comprising about 1 mol% to about 20 mol% oxygen to form stabilized pitch particles.

Abrégé
A method for controlling the growth of a hydraulic fracture using a stress shadow generated during a hydraulic fracturing operation includes selecting a stage pair including a first stage and a second stage for which hydraulic fractures are to be generated via a hydraulic fracturing operation. The method also includes hydraulic fracturing the first stage to generate a corresponding first hydraulic fracture and controlling a magnitude of a stress shadow originating from the first hydraulic fracture by varying at least one parameter of the hydraulic fracturing operation, where the stress shadow is controlled so as to provide a second hydraulic fracture of a target fracture shape for the second stage. The method further includes hydraulic fracturing the second stage to generate the second hydraulic fracture with the target fracture shape.
