Methods are provided for upgrading of pyrolysis carbon in order to allow for conversion of the pyrolysis carbon into higher value products. Instead of attempting to convert methane into a high value carbon product (such as carbon nanotubes) and Hin a single reaction step, pyrolysis conditions can be used to form Hand pyrolysis carbon. The pyrolysis carbon can then be treated in order to convert the pyrolysis carbon (H to C atomic ratio of less than 0.20) into a product with a higher hydrogen content (H to C atomic ratio of 0.25-0.9 or 2.0-7.0 wt % H). The treatment can correspond to exposing the pyrolysis carbon with hydrogen in the presence of a catalyst, exposing the pyrolysis carbon to conditions for alkylation, or a sequential combination thereof. This can convert the pyrolysis carbon into heavy hydrocarbon products that are resin-like solids at room temperature.

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.
