Methods for producing advanced carbon materials from 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.
ELECTROLYSIS METHODS THAT UTILIZE CARBON DIOXIDE FOR MAKING COATED NANOCARBON ALLOTROPES
The embodiments of the present disclosure relate to a method and apparatus for producing a carbon nanomaterial product (CNM) product that may comprise carbon nanotubes and various other allotropes of nanocarbon. The method and apparatus employ a consumable carbon dioxide (CO.sub.2) and a renewable carbonate electrolyte as reactants in an electrolysis reaction in order to make CNTs. In some embodiments of the present disclosure, operational conditions of the electrolysis reaction may be varied in order to produce the CNM product with a greater incidence of a desired allotrope of nanocarbon or a desired combination of two or more allotropes.
PROCESS FOR GRAPHENE-LIKE CARBON COATING ON SUBSTRATES
The present disclosure relates to a patternable process for coating functional and adherent graphene-like carbon on multiple substrate types using CO.sub.2 laser-induced photothermal pyrolysis in scanning mode. The poly furfuryl alcohol (PFA) synthesised via low-temperature polymerisation of furfuryl alcohol precursor without any additives was used to form graphene-like carbon material.

ORGANIC NON-WETTABLE SUPERHYDROPHOBIC FULLERITE FILMS
A method of producing an organic non-wettable superhydrophobic fullerite film is presented. Non-wettable superhydrophobic fullerite films can be easily produced by growing nanofullerites via a sonication coupled crystallization protocol followed by multiple washings to obtain a pellet of nanofullerites. The pellet is aged for at least several weeks to allow for agglomeration into a gel which may then be applied to a substrate as a non-wettable superhydrophobic fullerite film.

SUSTAINABLE, FACILE SEPARATION OF THE MOLTEN CARBONATE ELECTROLYSIS CATHODE PRODUCT
A process for the separation of electrolyte from the carbon in a solid carbon/electrolyte cathode product formed at the cathode during molten carbonate electrolysis. The processes allows for easy separation of the solid carbon product from the electrolyte without any observed detrimental effect on the structure and/or stability of the resulting solid carbon nanomaterial.
Methods for reducing carbon oxides with non ferrous catalysts and forming solid carbon products
A method of reducing a gaseous carbon oxide includes reacting a carbon oxide with a gaseous reducing agent in the presence of a non-ferrous catalyst. The reaction proceeds under conditions adapted to produce solid carbon of various allotropes and morphologies, the selective formation of which can be controlled by means of controlling reaction gas composition and reaction conditions including temperature and pressure. A method for utilizing a non-ferrous catalyst in a reactor includes placing the catalyst in a suitable reactor and flowing reaction gases comprising a carbon oxide with at least one gaseous reducing agent through the reactor where, in the presence of the catalyst, at least a portion of the carbon in the carbon oxide is converted to solid carbon and a tail gas mixture containing water vapor.
