Abstract:
A method of generating ozone from oxygen-containing gases by silent electric discharge in an arrangement with at least one gap defined by an electrode and a dielectric that separates the gap from another electrode, an electrically and thermally conductive gas-permeable arrangement being disposed in the gap and being in electrical and thermal contact with the electrode, the gas-permeable arrangement forming a spacer and having a regular structure completely filling the gap and contacting the dielectric and an internal cohesion and that comprises a plurality of hollow spaces, the method comprising the steps of:applying a same electrical potential to all of the hollow spaces;maintaining a silent electrical discharge in the hollow spaces according to a hollow-cathode effect;causing oxygen-containing gas to flow through the gap and allowing the oxygen-containing gas to flow from one hollow space to another; andexposing the oxygen-containing gas to the silent electrical discharge to convert the oxygen-containing gas into ozone.
