Embodiment 1

[0091] Dielectric barrier discharges were generated at 100% duty cycle, 21 kHz power frequency and 3.80 kV electrode voltage using electrodes with a diameter of 60 mm. Prepare a series of gas mixtures containing different ratios of oxygen and carbon dioxide gases. The gas mixture is prepared in a sealed polyethylene bag and subjected to a dielectric barrier discharge to generate ozone inside the bag.

[0092] The discharge was performed for a fixed period of 60 seconds and then the ozone concentration was measured using a 2B Technologies 106-MH ozone meter.

[0093] exist figure 1 In , the ozone concentrations obtained from different mixtures are plotted relative to the increasing amount of carbon dioxide or nitrogen in the gas mixture (reactant).

[0094] Such as figure 1 As shown and as expected, as the amount of oxygen in the reaction chamber decreases, the ozone concentration decreases. However, since the oxidizing gas contributes to the ozone yield, even with a lower ...

Abstract

A method of preparing ozone comprising: providing a gas mixture comprising: a) vol.% to 50 vol.% oxygen; b) 50 vol.% to 95 vol.% of an oxide gas; and subjecting the gas mixture to an ozone generatingprocess to produce ozone is disclosed as well as the use of a composition comprising a) 5 vol.% to 50 vol.% oxygen; b) 50 vol.% to 95 vol.% of an oxide gas; as reactant in the preparation of ozone.

Description

technical field [0001] The invention relates to a method for producing ozone. More specifically, the present invention relates to a method for producing ozone using a gas mixture comprising oxygen and an oxidizing gas, and the use of a specific gas mixture as a feedstock in an ozone generating process to convert oxygen into ozone. Background technique [0002] Ozone has been used for many years to reduce bioburden in food, medical device and water disinfection. As a strong oxidizing agent, ozone is capable of inactivating a wide range of microorganisms, and it has been found difficult for microorganisms to develop resistance. [0003] The key advantage of ozone is that it is produced from oxygen and turns back to oxygen naturally, leaving no other residue. This makes ozone environmentally friendly compared to other compounds or technologies used instead. However, this natural variation in ozone prevents ozone from being produced at remote facilities and transported to the...
