Ozone Destruction Catalyst (GTODC-LC)

GTODC-LC catalyst uses honeycomb (foam) ceramic as the carrier and nano-composite metal oxide as the catalytically active component. The catalyst is mainly used for the purification of low and medium concentration ozone emissions. It can quickly catalyze and decompose ozone into non-toxic oxygen at room temperature. Its structure is honeycomb, with low gas resistance.

1, High-strength Structure

Using cordierite (2MgO·2Al2O3·5SiO2) ceramics as the base material, the compressive strength is 280~500 MPa. The tensile strength is 25-40 MPa. The bending strength is 50~60 MPa. The impact strength is 1.8~2.2 cm·kg/cm2. Coefficient of linear expansion (1.1~1.8)×10-6(20~100℃). The refractoriness is about 1400 ℃.

2, Firm Surface Coating

The ceramic carrier surface of the ozone destruction catalyst adopts a new in-situ growth technology. A catalytically active metal oxide coating is grown on the smooth ceramic surface. The firmness of the coating is much higher than that of the traditional dip coating technology. The catalyst was subjected to ultrasonic vibration in water for 30 minutes, and the peeling rate of the coating was less than 1%.

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.
