Hydrogen Peroxide Generation in Low Power Pulsed Water Spray Plasma Reactors

Abstract

The energy yield for hydrogen peroxide formation from pure water sprayed into a low power, pulsed, gliding arc plasma reactor under various experimental conditions was determined. The water flow rate, carrier gas flow rate, electrode shape, and pulse frequency were varied, all of which affect the overall power of the discharge. Results show that the energy yield for hydrogen peroxide formation increased as the mean discharge power decreased, and the trend was independent of the variables that affected the power when a pulsed power supply was utilized to generate the discharge.
