If air is used to generate ozone, which percentage of the air is usually converted to ozone?

When air is used as the feed gas to generate ozone, the typical conversion rate of air to ozone is around 1 - 3%. This conversion percentage reflects the efficiency of ozone generation processes, where only a small fraction of the oxygen in the air is actually transformed into ozone.

This range is a result of various factors, including the method used for ozone generation, the purity and concentration of the feed gas, and the operating conditions such as temperature and pressure. The process involves using electrical discharge or UV radiation to split oxygen molecules into individual atoms, which can then bond with other oxygen molecules to form ozone (O3). Since air is primarily composed of nitrogen, oxygen makes up only a small portion of the air's volume, limiting the amount of ozone produced from the total volume of air processed.

A percentage like 1 - 3% signifies how typically only a fraction of the available oxygen can be effectively converted into ozone under standard conditions, emphasizing the efficiency of the ozone generation method being employed.
