A system and method for performing plasma reactions creating a plasma area in a gas adjacent to a liquid. An embodiment of the plasma reactor includes a housing with an internal reaction chamber, first and second inlet paths to the reaction chamber, and electrodes for producing an electric field. The system may optionally further include a pre-ionization electrode and pre-ionization electric field for pre-ionizing a feed gas prior to entry into a reaction chamber. The reactor uses plasma to ionize gas adjacent with the liquid. The ionized gas reacts with the liquid to form an effluent. Exemplary uses of the plasma reactor include ionic injection, gas dissociation, liquid re-formation, and liquid dissociation.

The present disclosure relates to a system and method for synthesis of condensed, nano-carbon materials to create nanoparticles. In one embodiment the system may have a source of liquid precursor, a flow control element and a shock wave generating subsystem. The flow control element is in communication with the source of the liquid precursor and creates a jet of liquid precursor. The shock wave generating subsystem drives a shock wave through at least a substantial portion of a thickness of the jet of liquid precursor to sufficiently compress the jet of liquid precursor, and to increase a pressure and a temperature of the jet of liquid precursor, to create solid state nanoparticles.

An in-liquid plasma generation device includes a housing which holds a liquid in an internal space, a gas supply tube which includes an opening in the internal space and discharges a gas into the liquid through the opening, a first electrode which has projecting part projecting into the internal space via the opening from inside of the gas supply tube, the projecting part including a conductor covered by a dielectric, a second electrode which surrounds the projecting part of the first electrode and includes a conductor isolated from the liquid by a dielectric, and a voltage applier which applies a voltage to between the first electrode and the second electrode. A space between the projecting part and the second electrode is a flow passage in which the gas discharged from the opening flows.

System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.
