Abstract: Proppant particulates are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. In complex fracture networks, it can be difficult to deposit proppant particulates fully within the fractures. In addition, low crush strengths may result in problematic fines formation. Polyaromatic hydrocarbons, commonly encountered in various refinery process streams, may serve as an advantageous precursor to proppant particulates. Polyaromatic hydrocarbons may undergo crosslinking under acid-catalyzed conditions in an aqueous solvent in the presence of a surfactant to form substantially spherical particulates that may serve as effective proppant particulates during fracturing operations. In situ formation of the proppant particulates may take place in some cases.

Abstract: Processes for chemically treating mixed aromatic feedstock to form thermoset aromatic resins are provided. The thermoset materials possess high compressive strength and find particular use in load-bearing applications, for example, infrastructure applications, as proppants, and as components in composite materials.

Abstract: A variety of methods are disclosed, including, in one embodiment, a method of making crosslinked aromatic resin beads comprising: contacting a linker agent and a catalyst with an aromatic feedstock at a first temperature effective to react the linker agent with molecules in the aromatic feedstock to form a pre-polymer mixture; combining the pre-polymer mixture with an antisolvent; agitating the pre-polymer mixture and the antisolvent; and heating the pre-polymer mixture and antisolvent to a second temperature to react the pre-polymer mixture to form crosslinked aromatic resin beads, wherein the pre-polymer mixture is dispersed as droplets in the anti solvent.
