  • Patent number: 11254569
    Abstract: In a method and device for conversion of water into hydrogen peroxide (H2O2), a corona discharge zone is generated between a first electrode (10) and a second electrode (6) one of which is insulated and another of which is not insulated and wherein a respective surface of each of the electrodes face one another. The first electrode (10) is rotated so as to induce relative rotation between the first electrode and the second electrode; and liquid water is conveyed on to a surface of the first electrode facing the second electrode close to the axis of rotation (4) of the first electrode whereby the liquid water advances outward through the corona discharge zone towards a periphery of the first electrode under the action of centrifugal force caused by rotation of the first electrode.
    Type: Grant

  • Patent number: 10138562
    Abstract: A method and device for conversion of water into hydrogen peroxide, wherein a corona discharge zone is generated between a rotating electrode formed as a hollow rotor of a centrifugal fan and a fixed electrode. The rotating electrode is rotated relative to an insulation layer of the fixed electrode, and high voltage AC power is applied to the fixed electrode while conveying vapor through the corona discharge zone. In one aspect, the novelty resides in using the rotating electrode for conversion of water to vapor. In another aspect, conductivity between the two electrodes induces electrolysis, which is used for high voltage AC transmission to the rotating electrode.
