Reactor for carbon nanotube and nanofiber production

Systems and methods are provided for production of carbon nanotubes and H.sub.2 using a reaction system configuration that is suitable for large scale production. In the reaction system, a substantial portion of the heat for the reaction can be provided by using a heated gas stream. Optionally, the heated gas stream can correspond to a heated H.sub.2 gas stream. By using a heated gas stream, when the catalyst precursors for the floating catalyst-chemical vapor deposition (FC-CVD) type catalyst are added to the gas stream, the gas stream can be at a temperature of 1000° C. or more. This can reduce or minimize loss of catalyst precursor material and/or deposition of coke on sidewalls of the reactor. Additionally, a downstream portion of the reactor can include a plurality of flow channels of reduced size that are passed through a heat exchanger environment, such as a shell and tube heat exchanger. This can provide cooling of the gas flow after catalyst formation to allow for carbon nanotube formation, while also reducing the Reynolds number of the flow sufficiently to provide laminar flow within the region where carbon nanotubes are formed.

Systems and methods for eliminating carbon dioxide and capturing solid carbon are disclosed. By eliminating carbon dioxide gas, e.g., from an effluent exhaust stream of a fossil fuel fired electric power production facility, the inventive concepts presented herein represent an environmentally-clean solution that permanently eliminates greenhouse gases while at the same time producing captured solid carbon products that are useful in various applications including advanced composite material synthesis (e.g., carbon fiber, 3D graphene) and energy storage (e.g., battery technology). Capture of solid carbon during the disclosed process for eliminating greenhouse gasses avoids the inefficiencies and risks associated with conventional carbon dioxide sequestration. Colocation of the disclosed reactor with a fossil fuel fired power production facility brings to bear an environmentally beneficial, and financially viable approach for permanently capturing vast amounts of solid carbon from carbon dioxide gas and other greenhouse gases that would otherwise be released into Earth's biosphere.
