NOVELTY - The plasma gliding arc discharge reactor (805) comprises a housing having divergent electrodes supported by the housing, a pulsed power supply connected to the electrodes, a nozzle (800) that is coupled to the housing and directs a mixture of a carrier gas and a liquid to a region between the divergent electrodes to generate plasma in the region, and a pulsed pump that injects the liquid into the mixing chamber through a recurrence of discrete strokes. The nozzle comprises a first inlet (810) for receiving the carrier gas, and a second inlet (820) for receiving the liquid.    USE - Plasma gliding arc discharge reactor for generating reaction products such as hydrogen peroxide, hydrogen or nitrates (claimed), and for chemical transformations in liquids and gases.    ADVANTAGE - The plasma gliding arc discharge reactor can be efficiently and economically manufactured, and ensures sufficient and safe generation of the desired reaction products with high throughput.    DETAILED DESCRIPTION - The plasma gliding arc discharge reactor (805) comprises a housing having divergent electrodes supported by the housing, a pulsed power supply connected to the electrodes, a nozzle (800) that is coupled to the housing and directs a mixture of a carrier gas and a liquid to a region between the divergent electrodes to generate plasma in the region, and a pulsed pump that injects the liquid into the mixing chamber through a recurrence of discrete strokes. The nozzle comprises a first inlet (810) for receiving the carrier gas, a second inlet (820) for receiving the liquid, a mixing chamber (830) coupled to both the first inlet and the second inlet and configured to mix the carrier gas and the liquid before directing to the region, and an outlet (840) that is coupled to the mixing chamber and that directs the mixture of the carrier gas and the liquid to the plasma region. After exiting the mixing chamber, the mixture of the carrier gas and the liquid is an aerosolized spray in which the liquid is comprised of droplets. The liquid is water or combination of water and methanol. A flow rate of the liquid and the carrier gas is selected from several flow rates. The reactor has a confined configuration. Reaction products such as hydrogen peroxide, hydrogen or nitrates are generated in the reactor. An INDEPENDENT CLAIM is included for a method of generating reaction products such as hydrogen peroxide, hydrogen or nitrates in a gliding arc discharge reactor.
