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: Systems and methods are provided for production of renewable jet fuel and/or jet fuel blending component fractions. The systems and methods provide for formation of jet boiling range fractions via hydrodeoxygenation and catalytic dewaxing of bio-derived feeds. The systems and methods for reducing or minimizing recycle and/or forming only a jet boiling range product and a lower boiling range product can be facilitated based on selection of a suitable feedstock and/or based on selection of suitable reaction conditions and catalyst for the catalytic dewaxing.

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.

Abstract: Communication networks, relay nodes for communication networks, and methods of transmitting data among a plurality of relay nodes utilizing non-dispersive guided acoustic waves are disclosed herein. The communication networks include an elongate tubular body and a wireless data transmission network including a plurality of relay nodes. The relay nodes include an electro-acoustic transmitter array and an electro-acoustic receiver. The methods include inducing a first acoustic wave within the elongate tubular body with a first relay node, conveying the first acoustic wave along the elongate tubular body to a second relay node, and receiving the first acoustic wave with the second relay node. The methods further include inducing a second acoustic wave within the elongate tubular body with the second relay node, conveying the second acoustic wave along the elongate tubular body to a third relay node, and receiving the second acoustic wave with the third relay node.
