Abrégé
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.

222 sorption capacity is unexpected. Conventionally, even when high pore volume support materials are used to support an amine sorbent, only a limited amount of the amine sorbent can be supported on the support material before substantial losses of sorbent capacity occur relative to the amount of amine sorbent.

Abrégé
Monolith structures coated with porous solids are provided that can serve as structural materials for amine sorbents, such as polyamine sorbents. By using monolith structures that are coated with suitable porous solids, the sorption capacity of an amine sorbent material that is deposited on the monolith coated with the porous solid can be substantially maintained as the loading density of the amine is increased. This can allow for higher productivity sorption systems by allowing higher concentrations of amine to be effectively used while still substantially maintaining the favorable sorption characteristics of the amine sorbent.

Abrégé
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.

Abrégé
A method and system for seismic anomaly detection is disclosed. Hydrocarbon prospecting relies on accurate modeling of subsurface geologic structures and detecting fluid presence in the geologic structures. For example, a seismic survey is gathered and processed to create a mapping of the subsurface region. The processed data is then examined, such as by comparing pre- or partially-stacked seismic images, in order to identify subsurface structures that may contain hydrocarbons. Instead of relying on engineered image attributes, which may be unreliable and biased, to identify anomalous features, an unsupervised machine learning framework is used to learn the relationships among partially-stack images or among pre-stack images to detect the anomalous features, and in turn hydrocarbon presence.

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.
