Abstract
A method of producing advanced carbon materials can include providing coal to a processing facility, beneficiating the coal to remove impurities from the coal, processing the beneficiated coal to produce a pitch, and treating the pitch to produce an advanced carbon material such as carbon fibers, carbon nanotubes, graphene, resins, polymers, biomaterials, or other carbon materials.
Claims14
A mesophase coal pitch comprising at least 90% of aromatic hydrocarbons, wherein the mesophase coal pitch comprises a melting point of greater than about 343° C. (650° F.).
A method of producing a mesophase coal pitch, comprising:
- providing an amount of coal to a processing facility;
- beneficiating the amount of coal at the processing facility to remove impurities therefrom, wherein beneficiating the amount of coal includes heating the amount of coal to a first temperature for a first duration and heating the amount of coal to a second, higher temperature for a second duration;
- and
- processing the beneficiated amount of coal at the processing facility to produce an isotropic coal pitch from at least some of the amount of coal further processing the isotropic coal pitch to produce the mesophase coal pitch, wherein the mesophase coal pitch comprises at least 90% of aromatic hydrocarbons and comprises a melting point of greater than about 343° C. (650° F.).
