  • Patent number: 11787709
    Abstract: A method for reacting a liquid phase chemical species includes the steps of providing liquid phase containing at least one liquid phase chemical species, providing a gas phase, and providing a reactor vessel for containing the liquid phase and the gas phase. The liquid phase and the gas phase are placed in the reactor vessel so as to form a liquid-gas interface between the liquid phase and the gas phase within the reactor vessel. A pulsed discharge cathode and anode are provided for creating a pulsed discharge electric field at the liquid-gas interface. A pulsed power input to the pulsed discharge cathode and anode is provided, thereby creating a plasma comprising ions at the liquid-gas interface. A secondary electric field is directed transverse to the liquid-gas interface, wherein the secondary electric field will drive ions from the gas phase into the liquid phase to react with the liquid phase species.

  • Publication number: 20210206667
    Abstract: A reactor system for reacting liquid phase chemical species in a liquid includes a reactor vessel for containing the liquid phase and a gas phase. The reactor vessel can have a gas injection port, a gas exit port, and a liquid-gas interface location within the reactor vessel. A pulsed discharge cathode and anode are provided for creating a pulsed discharge electric field at the liquid-gas interface location. A pulsed discharge power supply delivers a pulsed power input to the pulsed discharge cathode and anode, and thereby creates a plasma comprising ions at the liquid-gas interface location. A secondary electric field source is provided for directing a secondary electric field transverse to the liquid-gas interface. The secondary electric field will drive some of the ions from the gas phase into the liquid phase to react with the liquid phase chemical species. A method for reacting a liquid phase chemical species is also disclosed.
