Abstract
Methods, systems, and devices are described to fabricate precursor intermediaries and carbon fiber or graphene materials. In one aspect, a method to fabricate an acryl-modified polymer includes obtaining a hydrocarbon substance from one or both of a waste stream or natural gas, separating gases from the hydrocarbon substance to form hydrogen gas and a carbonaceous gas including one or more of methane, butane, or ethane, dehydrogenating the carbonaceous gas by adding heat to form a dehydrogenated carbon material, and reacting the dehydrogenated carbon material with a nitrogen material including one of ammonia or urea to produce polyacrylonitrile (PAN).
Claims17
A method to fabricate carbon fibers or graphene, comprising the steps of:
- obtaining a precursor material from a hydrocarbon substance from one or both of a waste stream or a fossil fuel source, wherein obtaining the precursor material comprises:
- separating gases from the hydrocarbon substance to form hydrogen gas and a carbonaceous gas;
- dehydrogenating the separated carbonaceous gas by adding heat to form a dehydrogenated carbon material;
- and
- reacting the dehydrogenated carbon material with a nitrogenous material to produce the precursor material,
- processing the precursor material to produce carbon fibers,
- wherein processing the precursor material causes nitrogen and hydrogen to be released.
A method to produce a fuzzy carbon fiber composition comprising the steps of:
- forming a precursor into a tensioned fiber;
- dehydrogenating the tensioned fiber to produce a carbon graphite fiber;
- developing architectural constructs on the tensioned carbon fiber to produce a fuzzy fiber composition.
