Home Products GTODC-GL Catalyst


Ozone Destruction Catalyst (GTODC-GL)

GTODC-GA uses activated alumina as the support and nanocomposite metal oxide as the catalytically active component. The catalyst can be used for the purification of higher concentration ozone emissions. It can quickly catalyze the decomposition of ozone into non-toxic oxygen at room temperature. The catalyst is spherical particles with the characteristics of larger specific surface area.

1, Activated Alumina Support

Activated alumina has a rich pore structure, which allows the active components of the catalyst to be dispersed in the carrier and improves the thermal stability and anti-toxicity of the catalyst. In addition, it has high temperature resistance, chemical resistance and high mechanical strength.

2, High Temperature Resistance

GTODC-GL catalyst does not contain carbon elements, all materials are inorganic, and will not be damaged by heat when decomposing and eliminating high-concentration ozone.

3, High Catalytic Activity

The catalyst adopts a composite multi-element catalyst system. After years of technical research and use verification, the catalyst has high catalytic activity and high stability.

4, High moisture Resistance

The coating of the ozone catalyst adopts rare earth composite oxide with high catalytic activity, which has a stable structure and can resist high humidity.


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.
