Abstract: An apparatus for forming nano-structures of carbon solids includes a reactor chamber into which extends a plasma torch configured to generate a plasma plume that extends into the interior of the reactor chamber. CO2 from is applied to the plasma plume where the CO2 is dissociated into carbon and oxygen. A plurality of nozzles also extends into the reactor chamber, which sprays liquid water on the plume, cooling at least a portion of the carbon causing it to form solid carbon nano-structures in a mixture of liquid water. The mixture is conveyed to a flocculation tank.

Abstract: A plasma generator for three phase mains alternating current operation has three plasma generation tubes interconnected with a nozzle, each plasma generation tube having a plasma initiator for forming a plasma into an electrode ring, the electrode ring including substantially tangential gas introduction orifices which cause gas entering the electrode ring to helically rotate. Each of the electrode rings is coupled to a unique one of the three phases of AC voltage supply, such that when the initiator plasma is introduced into one of the electrode rings, a plasma discharge occurs with a path from the electrode ring, through the plasma generation tube, and to a different electrode ring.
