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, carbon fibers, polymers, biomaterials, or other carbon materials.
Claims20
A method of producing carbon fiber, comprising:
- providing an amount of raw coal, the raw coal including one or more impurities therein;
- beneficiating the amount of raw coal to selectively removing at least a portion of some of the one or more impurities in the raw coal to form beneficiated coal;
- processing the beneficiated coal to produce an amount of pitch;
- and
- modifying at least some of the pitch to produce the carbon fiber;
- wherein the carbon fiber includes a selected amount of a remainder of the one or more impurities that were not removed while beneficiating the amount of the raw coal, processing the beneficiated coal, and modifying at least some of the pitch.
A method of producing an advanced carbon material at a single processing facility, comprising:
- providing an amount of raw coal to the single processing facility, the raw coal including one or more impurities therein;
- beneficiating the amount of raw coal at the single processing facility to selectively removing at least a portion of some of the one or more impurities in the raw coal to form beneficiated coal;
- processing the beneficiated coal at the single processing facility to produce an amount of pitch;
- and
- modifying at least some of the pitch at the single processing facility to produce the one or more resins;
- wherein the one or more resins include a selected amount of a remainder of the one or more impurities that were not removed while beneficiating the amount of the raw coal, processing the beneficiated coal, and modifying at least some of the pitch.
The method of claim 16, wherein beneficiating the amount of raw coal includes removing at least 75 wt. % of at least one of mercury, arsenic, cadmium, water, or volatile compounds.
Carbon fiber formed from coal comprising a selected amount of a remainder of one or more impurities that were initially present in raw coal.
