Abstract
Methods and systems are described for the synthesis of graphene, synthetic graphite, and other carbon allotropes. Thus, the method describes a method to synthesize carbon nanostructures and synthetic graphite by using unrecyclable materials, such as plastic wastes (i.e., Polypropylene, Styrene, Polyethylene, Poly Vinyl Chloride, PVDF, tires, etc.), Liquid wastes (i.e. tank bottoms, PVDF liquid foams, contaminated oils, etc.) (unrecyclable carbons) regardless of its state, cleanliness, or whether it is contaminated with other byproducts.
Claims20
A method for manufacturing carbon material, comprising:
- mixing a carbon precursor with a catalyst in a controlled oxygen free environment, where the reaction is carried-out at a range from about 600° C. to 1400° C.
A method of synthesizing carbon, the method comprising:
- mixing a feed stock with molten aluminum;
- injecting the molten aluminum and feed stock mixture into a reaction vessel containing further molten aluminum, wherein the injection occurs below the surface of the molten aluminum in the reaction vessel;
- and
- reacting the feed stock with the molten aluminum, such that one or more carbon-containing products are formed.
A reaction vessel for reacting a carbon precursor with molten metal, the reaction vessel comprising:
- a reaction vessel wall;
- a refractory material lining an inside of the reaction vessel wall;
- a cooling plate attached to an outside of the reaction vessel wall, wherein the cooling plate forms a channel for a cooling fluid between the cooling plate and the reaction vessel wall;
- an aluminum feed line passing through to the reaction vessel wall;
- an injection line passing through the reaction vessel wall and having an outlet in the reaction vessel, and configured to carry the carbon precursor into the reaction vessel;
- and
- one or more collection lines passing through the reaction vessel wall and configured to collect one or more output products.
