Abstract: Nucleation enhancement and/or growth rate improvement of mesophase in pitch compositions derived from hydrocarbon feedstocks can be achieved by: reacting in a reaction zone a blend comprising an isotropic feed and a seeding agent, to produce a reacted pitch having a mesophase content of about 10 vol% to 100 vol%, based on the total volume of the reacted pitch, and a softening point (Tsp) below 400°C; wherein the seeding agent is about 50 wt% or less, based on the total weight of the blend; wherein the seeding agent has a mesophase content of about 0.01 vol% to 100 vol%, based on the total volume of the seeding agent.

Abstract: Systems and methods are provided for ozonolysis of polycyclic aromatic hydrocarbons (PAHs) in a liquid CO2 reaction environment. It has been unexpectedly discovered that oxygen- containing functional groups can be added to PAH substrates while substantially avoiding combustion reactions and while reducing or minimizing formation of energetic intermediates. Because the formation of energetic intermediates is minimal, the ozonolysis can be performed at temperatures near ambient (e.g., between -10°C and 50°C) while still achieving a satisfactory safety profile. In various aspects, ozonolysis can occur while forming a reduced or minimized amount of water, such as forming substantially no water in the reaction environment.

Abstract: Provided herein are methods of making metal-organic frameworks comprising forming a suspension capable of producing metal-organic frameworks; inducing flocculation of the suspension to form a plurality of flocs; allowing the flocs to separate from the suspension and produce a solid phase comprising metal-organic frameworks and a supernatant liquid phase; separating the solid phase from the supernatant liquid phase; and recovering the metal-organic frameworks from the solid phase. The present methods include dissolving a metal salt and at least one ligand in a solvent to form the suspension.

Abstract: Ink compositions are provided for using solvent-based additive manufacturing (SBAM) techniques to form contactor structures and/or structures for use in an adsorption or absorption contactor. Methods forming a contactor using SBAM are also provided. The ink compositions can include a substantial content of adsorbent particles to provide enhanced adsorption by a contactor. Metal organic framework (MOF) structures and zeotype framework structures are examples of types of adsorbent particles that can be incorporated into an ink composition for forming a contactor structure by SBAM. The ink can further include a polymeric component that can serve as the structural component of a polymeric structural material produced by the additive manufacturing method. Such a structural material can correspond to a polymeric material with incorporated adsorbent particles. In some aspects, the polymeric structural material and/or the adsorbent particles can have selectivity for adsorption of CO2 from a process fluid flow.

Abstract: Fiber compositions are provided that incorporate metal organic framework (MOF) materials into the polymeric matrix of the fiber. The metal organic framework materials can be incorporated by including MOF particles into a "dope" or synthesis solution used to form the fiber. The dope solution can then be used to form fibers that include 5.0 wt% or more of MOF in the resulting polymeric structural material of the fiber, relative to a weight of the fibers. In some aspects, the metal organic framework material can correspond to a MOF with selectivity for adsorption of CO2.
