Ozone Destruction Catalyst (GTODC-GM)

GTODC-GM catalyst is made of manganese-based composite metal oxide with ozone catalytic decomposition activity. The catalyst is mainly aimed at the purification of medium and high concentration ozone emissions. It can quickly catalyze and decompose ozone into non-toxic oxygen at room temperature. The catalyst does not contain carbon elements and there is no risk of explosion.

1, More Active Materials

GTODC-GM is made of pure active component (manganese-based composite metal oxide) without support material. Under the same working conditions, its ozone decomposition rate is higher and more stable than similar products.

2, More Processing Power

GTODC-GM ozone destruction catalyst is mainly designed and developed for the decomposition of high-concentration ozone (specially suitable for O3≥500ppm), and it is also safe and effective for the purification of medium and low-concentration ozone (O3<500ppm).

3, High Temperature Resistance

GTODC-GM catalyst does not use carbon, which will not cause a large amount of heat to be generated during the ozone decomposition process and cause the catalyst to burn and pulverize.

4, High Moisture Resistance

GTODC-GM catalyst is made of a composite metal oxide with catalytic activity, and it works normally in an environment with a relative humidity of 90%, and its service life is greatly increased.


1, Catalyst Installation

When the ozone destruction catalyst is used in the reactor, the minimum thickness of the catalyst layer is 50mm, the gas pipe does not flow shortly and the air is leaked, and all the gas passes through the catalyst layer.

2, Particle Filtration

Before the exhaust gas enters the catalyst layer, it is necessary to filter the particulate matter to avoid long-term accumulation of dust on the catalyst and cause the catalyst to fail.

3, Catalytic Temperature

The catalyst can catalyze the decomposition of ozone into oxygen at room temperature. Appropriate heating can help increase the rate of catalytic reaction. The effect is better when used at (40~80℃).

4, Restore Catalytic Activity

After the catalyst has been used for a certain period of time (for example, about one year), if the activity of the catalyst is found to be reduced due to the long-term accumulation of adsorbed moisture, the catalyst can be taken out, dried in an oven at 100°C for 6 hours or more, and then reloaded for use.
