    Abstract: Gaseous ozone is formed by vaporising a stream of liquid oxygen in a heat exchange coil and passing it through an ozonator 34 in which it is subjected to a silent electrical discharge. The oxygen enters the ozonator 34 at a temperature below ambient. This sub-ambient temperature is created by evaporating liquid oxygen in the stream of oxygen in a chamber 24 upstream of the ozonator 34. Operating the ozonator 34 in such a way enhances the yield of ozone.

    Abstract:  排ガス中のNOxをN 2 に還元可能な選択還元型触媒(19)がエンジン11の排気管(16)に設けられる。流体供給手段(21)は選択還元型触媒より排ガス上流側の排気管に臨む流体噴射ノズル(23)を有する。この流体供給手段は上記流体噴射ノズルから選択還元型触媒で還元剤として機能する尿素系流体(22)を排気管に供給するように構成される。オゾン供給手段(41)は選択還元型触媒より排ガス上流側であって流体噴射ノズルより排ガス上流側又は排ガス下流側の排気管に臨むオゾン噴射ノズル(43)を有する。このオゾン供給手段は上記オゾン噴射ノズルから排ガス中のNOをNO 2 に酸化可能なオゾン(42)を排気管に供給するように構成される。 排ガス温度が低いときであってもNOxを低減し、これにより低温から高温にかけて広い排ガス温度範囲でNOxを効率良く低減する。

    Abstract: In a closed ozone generator unit (2) oxygen gas is transformed into ozone gas by means of alternating current, the oxygen gas being substantially pressurized before entry into the unit (2). The unit is exposed to an external pressure substantially equal to or higher than the pressure of the oxygen gas.

    Abstract: A method of generating ozone by supplying high-purity oxygen gas to a discharge type ozonizer while preventing a decrease in ozone concentration without adding nitrogen gas. The method comprises supplying high-purity oxygen gas from an oxygen gas source 2 to an ozonizer 1, wherein the high-purity oxygen gas to be fed to the ozonizer is passed through a humidifier 4 to humidify it. By this humidification, the content of water in the high-purity oxygen gas to be fed to the ozonizer 1 is regulated to 0.05 to 40 ppm.

    Abstract: The present invention relates to an apparatus (10) and method for producing ozone from a feed gas containing molecular oxygen by means of a corona discharge. The apparatus (10) and method comprise passing the feed gas (220) between two concentric tubes (20, 60) of a dielectric material. The inner tube (20) contains an electrode (30) with a plurality of windings of a conductive wire electrode around its inner surface (21) or a central rod inside its inner surface (21). The outer tube (60) has a plurality of windings (70) of a conducting wire electrode around its outer surface (62). Both electrodes are connected to a high voltage AC electric current device (280), whereby the current flowing between the electrodes (30, 70) through the dieletric tubes (20, 60) and the passing feed gas converts at least some of the molecular oxygen in the feed gas to ozone. This method and apparatus (10) for generating ozone have the advantages of being low cost, reliable, energy efficient, simple, compact, and easy to use and maintain.
