Abstract: Processes for chemically treating polyaromatic feedstock to form aromatic-containing oligomers or polymers are provided. The processes are characterized by treatment of a plurality of different polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in polyaromatic feedstock with a first reagent so as to functionalize the molecules. Further treatment in a second step affords oligomeric or polymeric products which may be crosslinked. The products may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.

Abstract: Methods for determining nitrogen and/or sulfur containing surfactant residual concentrations in oil and/or water phases of an oil and water system, particularly produced oil and water from an oil or gas well, are provided. The methods utilize pyro-chemiluminescence/pyro-fluorescence techniques which quantify the total residual surfactants in both oil and water phases. The methods may be applied broadly in areas where quantifying or monitoring surfactant concentrations in solution is required.

Abstract: Epoxide functionalized polyaromatic feedstocks and processes for their preparation are described. The processes involve functionalizing polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in petroleum or petrochemical streams with epoxide. The epoxide functionalized poly aromatic feedstock can be further treated so as to effect oligomerization or polymerization. The oligomers or polymers may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.
