Abstract: Catalyst systems are provided, along with corresponding methods, for single stage conversion of synthesis gas to fuel boiling range products with increased selectivity for either naphtha production (C5-C9) or distillate production (C10-C20). The increased selectivity for naphtha production or distillate production is provided in conjunction with a reduced selectivity for higher boiling range components (C21+).

Abstract: A method and apparatus for liquefying a feed gas stream comprising natural gas and carbon dioxide. A method includes compressing an input fluid stream to generate a first intermediary fluid stream; cooling the first intermediary fluid stream with a first heat exchanger to generate a second intermediary fluid stream, wherein a temperature of the second intermediary fluid stream is higher than a carbon dioxide-freezing temperature for the second intermediary fluid stream; expanding the second intermediary fluid stream to generate a third intermediary fluid stream, wherein the third intermediary fluid stream comprises solid carbon dioxide; separating the third intermediary fluid stream into a fourth intermediary fluid stream and an output fluid stream, wherein the output fluid stream comprises a liquefied natural gas (LNG) liquid; and utilizing the fourth intermediary fluid stream as a cooling fluid stream for the first heat exchanger.

Abstract: Systems and methods are provided for performing direct air capture using a rotary sorbent bed configuration. The rotary sorbent bed is supported on a wheel that serves as a framework structure for supporting the sorbent bed. The sorbent bed can include one or more monoliths that form the support material for the sorbent bed, and a sorbent supported on the one or more monoliths. The rotational path of the sorbent bed passes through the enclosure that allows for sealing of the portion of the sorbent bed within the enclosure. Optionally, the enclosure can contain a plurality of sub-zones that facilitate temperature control and/or pressure control within the enclosure while allowing for recovery of a high purity CO2 stream from the desorption zone. The rotary sorbent bed configuration can allow for continuous or semi-continuous capture of CO2 while reducing or minimizing contact of the sorbent bed with oxygen at elevated temperature.

Abstract: A methodology using an interwell connectivity model for hydrocarbon management is disclosed. The interwell connectivity model may include interwell connectivity metrics indicative of fluid interconnectivity amongst pairs of wells and may be used as predictive or prescriptive for enhanced oil recovery (EOR). As predictive, the interwell connectivity model may be used to determine an effect of gas injection into the reservoir on one or more aspects of EOR, such as reservoir pressure or production rates. As prescriptive, the interwell connectivity model may be used to improve or optimize various stages of EOR, such as during drilling or construction of the extraction site, during primary depletion, or during one or more huff-and-puff cycles.

Abstract: The present disclosure relates to processes for forming alumoxanes and catalyst systems thereof for olefin polymerization. In at least one embodiment, a process includes forming a solution by, in an aliphatic hydrocarbon having a boiling point of less than about 70 degrees Celsius, introducing at least one hydrocarbyl aluminum with at least one non-hydrolytic oxygen-containing compound and a support material. The molar ratio of aluminum to non-hydrolytic oxygen in the solution is greater than or equal to 1.5, and the combining is conducted at a temperature of less than about 70 degrees Celsius. The process includes distilling the solution at a pressure of greater than about 0.5 atm to form a supported alumoxane precursor. The process further includes heating the supported alumoxane precursor to a temperature greater than the boiling point of the aliphatic hydrocarbon fluid and less than about 160 degrees Celsius to form a supported alumoxane.

Abstract: Methods are provided for synthesizing metal-organic framework compositions using synthesis mixtures with elevated solids content and/or elevated kinematic viscosity. The methods can allow for formation of MOF-274 metal-organic framework compositions, such as EMM-67 (a mixed-metal MOF-274 metal-organic composition). More generally, the methods can allow for formation of MOF structures that include multi-ring disalicylate organic linkers using synthesis mixtures that contain a reduced or minimized amount of solvent, such as down to having substantially no solvent in the synthesis mixture.

Abstract: Selective removal of non-aromatic hydrocarbons from a xylene isomerization process for para-xylene production is accomplished using a membrane unit positioned within a xylene recovery loop. The membrane unit may include a one-stage or multi-stage (e.g., two-stage) membrane system and may be configured to separate a membrane unit product stream from a non-aromatics rich stream, which can be removed from the xylene recovery loop. The membrane unit may have a xylene permeance of about 60 gm/m2/hr/psi and a xylene to non-aromatic permeance ratio of about 15.
