Abstract: Systems and methods for plasma based synthesis of graphitic materials. The system includes a plasma forming zone configured to generate a plasma from radio-frequency radiation, an interface element configured to transmit the plasma from the plasma forming zone to a reaction zone, and the reaction zone configured to receive the plasma. The reaction zone is further configured to receive feedstock material comprising a carbon containing species, and convert the feedstock material to a product comprising the graphitic materials in presence of the plasma.

Abstract: A nanocarbon material includes agglomerate nanostructures made of aggregates of: (i) graphene nanostructures having at least partially crumpled morphology, and (ii) clusters of at least one carbon material. The carbon material may have a graphitic structure. At least a portion of the graphitic structure may be at least partially hollow and have at least one winged protrusion. Optionally, the nanocarbon material may be part of a composition that includes a dispersion medium or a cementitious material. Methods of making such a composition are also disclosed.

Abstract: A non-thermal plasma is generated to selectively convert a precursor to a product. More specifically, plasma forming material and a precursor material are provided to a reaction zone of a vessel. The reaction zone is exposed to microwave radiation, including exposing the plasma forming material and the precursor material to the microwave radiation. The exposure of the plasma forming material to the microwave radiation selectively converts the plasma forming material to a non-thermal plasma including formation of one or more streamers. The precursor material is mixed with the plasma forming material and the precursor material is exposed to the non-thermal plasma including exposing the precursor material to the one or more streamers. The exposure of the precursor material to the streamers and the microwave radiation selectively converts the precursor material to a product.

Abstract: System and methods for plasma treatment of a fluidized bed of particles are disclosed. The systems include an energy coupling zone configured to generate a plasma from microwave radiation and an interface element configured to propagate the plasma from the energy coupling zone to a reaction zone. The reaction zone is configured to receive the plasma, receive a plurality of reactant particles in a fluidization plane direction from a fluidization assembly positioned below the reaction zone, and form a product in presence of the plasma. The fluidization plane is substantially perpendicular to the propagated plasma.

Abstract: Systems and methods for producing hydrogen and solid carbon from gaseous feedstock. The system includes a plasma reactor configured to receive and convert feedstock comprising hydrocarbons into acetylene-containing feed stream, and a refractory coupled to the plasma reactor that is configured to receive and decompose acetylene to hydrogen and solid carbon. The system is further configured to deliver one or more auxiliary feedstock comprising hydrocarbons directly to the refractory for decomposition into hydrogen and carbon. The energy required to decompose the auxiliary feedstock is provided by the energy released from decomposition of acetylene in the refractory.
