Reactor for liquid and gas and method of use

A method of injecting ionic particles from a gas using a reactor, comprising:

• inserting a liquid into a reaction chamber of the reactor that includes first and second electrodes connected to a power source;
• supplying a high-pressure flow of gas to the reaction chamber at a positive pressure relative to a pressure of the liquid in the reaction chamber, wherein the positive pressure enables the high-pressure flow of gas to enter the reaction chamber adjacent to the liquid and generate a plasma in the liquid;
• providing, with the power source, a plasma generating voltage of pulsed DC between the first and second electrodes and thereby producing an electric field, wherein at least a portion of the electric field is positioned within the reaction chamber;
• creating the plasma as the electric field ionizes the high-pressure flow of gas, the plasma comprising monatomic ions and molecular ions;
• and
• varying a strength of the electric field to control a ratio of molecular injection or infusion to ionic injection into the liquid and thereby controlling a ratio of the monatomic ions to the molecular ions, the electric field contacting the high-pressure flow of gas and the liquid within the reaction chamber and particles from the high-pressure flow of gas being transferred into the liquid forming an effluent comprising liquid infused with dissolved gas from the high-pressure flow of gas,
• wherein the strength of the electric field is varied by varying a voltage between the first and second electrodes by alternating between a first power level higher than a minimum voltage required to form the plasma and a second power level lower than the minimum voltage required to form the plasma.
