Things to note when using ozone oxidation catalysts

An ozone oxidation catalyst is a substance that can accelerate the ozone oxidation reaction. Its main components include active metal oxides, etc. It is widely used in sewage treatment, industrial waste gas treatment and other fields.

For example, in a certain sewage treatment plant, the use of ozone oxidation catalysts has greatly improved the sewage treatment efficiency. Organic matter that was originally difficult to degrade was quickly decomposed under the action of the catalyst, and the water quality was significantly improved. In the waste gas treatment of an industrial enterprise, the ozone oxidation catalyst successfully converted harmful waste gas components into harmless substances, greatly reducing the pollution of the waste gas to the environment.

The use of ozone oxidation catalysts has the advantages of high efficiency and the ability to reduce reaction conditions. However, you need to pay attention to some things during use: First, in addition to paying attention to ozone, you must also identify other components in the treatment gas. For example, sulfur-containing components will generate concentrated sulfuric acid to corrode catalysts and equipment. In the past, some companies failed to pay attention to the sulfur content in the gas, causing the catalysts and equipment to be corroded, causing considerable economic losses. Secondly, the gas must be pretreated before passing through the catalyst to filter particulate matter and liquid water to prevent the active ingredients from being covered and causing the catalyst to fail.

When the catalyst is poisoned, we need to deal with it according to different poisoning situations. If a catalyst is deactivated due to moisture, its original activity can usually be restored by drying at an appropriate temperature within the catalyst's operating range. Place the catalyst in an environment with good ventilation and a suitable temperature to allow the water to gradually evaporate, allowing the catalyst to regain its effectiveness. However, if there is irreversible poisoning caused by particulate matter or the catalyst is converted into other substances, the possibility of restoring activity is less likely and the catalyst often needs to be replaced. Because particulate matter will clog the pores of the catalyst and destroy its structure, the catalyst will not be able to function normally. The performance of the catalyst will also be fundamentally changed after chemical conversion.
