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: Processes and systems for producing olefin epoxides with three or more carbon atoms by oxidation of the corresponding branched hydrocarbons using oxygen are disclosed. An example process for producing olefin epoxides may include oxidizing a branched alkane to produce at least an organic hydroperoxide. The example process may further include epoxidizing a branched alkene by a catalytic reaction with least a portion of the organic hydroperoxide to produce at least an olefin epoxide and an alcohol. The example process may further include converting at least a portion of the alcohol to either additional branched alkane and/or additional branched alkene.

Abstract: Molten carbonate fuel cell structures are provided that include a structural mesh support layer at the interface between the surface of the cathode and the cathode current collector. The structural mesh layer can have a mesh open area of 25% to 45%. In addition to providing structural support, the structural mesh layer can reduce or minimize ohmic resistance at the interface between the cathode and the cathode current collector.

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: A method for determining the pore types of a core sample can include: determining a porosity of a core sample, wherein the core sample has a permeability of 10 mD or less; saturating the core sample with a NMR saturation fluid to achieve a saturated core sample; taking a NMR measurement of fluids in the saturated core sample; and deriving a volume for a pore type based on the porosity based on a correlation between the NMR measurement and a NMR signal to fluid volume calibration, wherein the pore type is selected from the group consisting of a nanopore, a micropore, a macropore, and any combination thereof.
