A method of preparing graphene from coal can include thermally processing raw coal and, after the coal has been at least partially cooled from thermal processing, forming reduced graphene oxide from the coal.

Methods for producing graphene from coal

Some protocols herein implement a first separation between first and second hybrid biochar production runs as a selective and conditional response to a sensor-based event whereby the first hybrid biochar production run is protected from a risk pertaining to the second hybrid biochar production run. Some variants implement synergies featuring biochar pyrolysis in close proximity to calcination or that otherwise facilitate durable 'green cement.' Some variants implement a production line that can switch between a first operating protocol calibrated to yield more power and a second operating protocol calibrated to reduce a biochar-blend-type inventory shortage. And in some variants steam from one or more heaters powers a first turbine and a first condenser downstream is positioned adjacent an oxygen-depleted vessel so that some of the thermal energy recaptured during condensation is applied to produce biochar.

Context-responsive systems and methods for operating a carbon removal facility

Embodiments of methods for improving mesophase pitch for carbon fiber production using supercritical carbon dioxide are described. The methods improve the relative amount and quality of mesophase pitch in feedstocks, such as coal tar, already having at least some mesophase pitch. One particular method includes performing a sCO2/toluene extraction on the coal tar to obtain a toluene insoluble fraction of the coal tar; mixing the toluene insoluble fraction with sCO2 to obtain a sCO2/toluene insoluble fraction mixture; and extruding the sCO2/toluene insoluble fraction mixture, thereby separating the sCO2 from the toluene insoluble fraction to obtain fibers of mesophase pitch.

A method of producing advanced carbon materials can include extracting a coal sample from a location, performing a spectral analysis on the coal sample, determining one or more desired advanced carbon materials based at least in part on spectral analysis, extracting an amount of coal from the location, beneficiating the amount of coal, and processing the beneficiated amount of coal to produce the one or more desired advanced carbon materials from at least some of the amount of coal.

Systems for producing advanced carbon materials at carbon source locations

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.

Methods for producing carbon fiber from coal

A method of producing at least one or more resins is disclosed. The method includes providing an amount of raw coal. The raw coal includes one or more impurities therein. The method also includes 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. Additionally, the method includes processing the beneficiated coal to produce an amount of pitch. The method further includes modifying at least some of the pitch to produce the one or more resins. 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.

Methods for forming resins and other byproducts from raw coal

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.

Methods for producing advanced carbon materials from coal

A method of forming high molecular weight ('HMW') coal tar can include combining supercritical carbon dioxide (sCO) and an amount of coal tar, and fractionating the amount of coal tar to form the HMW coal tar. The method can further include forming the amount of coal tar from coal. Forming the amount of coal tar from coal can include extracting the coal tar from an amount of coal using sCO.
