Ozone is a powerful oxidizing agent widely used for air and water purification, but its residual presence in exhaust streams can pose safety and environmental risks. To ensure complete and safe decomposition of ozone (O₃) into oxygen (O₂), the use of a high-performance Ozone Decomposition Catalyst is essential.
DEAI CHEM’s Ozone Decomposition Catalyst is specifically engineered for use in Ozone Destruct Systems, providing high efficiency, durability, and chemical stability under continuous operation.
1. Principle of Operation
In an ozone destruct system, ozone-containing air flows through a catalyst bed housed in a vertically oriented vessel. The system design typically includes:
1）Flow distribution zone for uniform gas contact
2）Optional pre-heater, used in humid applications to prevent condensation
3）Catalyst layer (DEAI CHEM Ozone Decomposition Catalyst) for efficient ozone conversion
As the gas passes through the catalyst bed, ozone (O₃) is decomposed into oxygen (O₂) according to the reaction:[2O₃ → 3O₂]
This reaction occurs spontaneously on the surface of the manganese dioxide/copper oxide catalyst without external power consumption, offering both energy efficiency and operational reliability.
2. Catalyst Characteristics
DEAI CHEM’s Ozone Decomposition Catalyst features optimized composition and structure to ensure high activity and long service life under demanding industrial conditions.
Chemical / Physical Data:
Composition: Manganese dioxide / copper oxide catalyst
Appearance: Black to dark brown granular form
Bulk Density: 0.72 – 0.92 g/cc
Surface Area: ≥ 200 m²/g
Weight Loss: < 1%
Available Particle Sizes:
4 × 8 mesh (4.8 mm × 2.4 mm)
8 × 14 mesh (2.4 mm × 1.4 mm)
This granular form ensures optimal gas contact and low pressure drop, making it suitable for both compact and large-scale ozone destruct units.
3. Recommended Operating Conditions
For best performance, the following operational guidelines are recommended:
1）Reactor Orientation: Vertical, with top-down airflow
2）System Materials: All contact materials must be ozone-compatible (e.g., stainless steel, PTFE)
3）Gas Hourly Space Velocity: ≤ 5,000 hr⁻¹
4）Linear Velocity: ≥ 0.66 m/s (2.2 ft/s)
5）Humidity Consideration: In humid conditions, pre-heat the air approximately 9°C (15°F) above ambient to avoid moisture condensation on the catalyst surface
Maintaining these parameters ensures maximum ozone conversion efficiency and prolonged catalyst lifetime.
4. Application Advantages
DEAI CHEM’s Ozone Decomposition Catalyst is designed to deliver:
1）High ozone conversion efficiency under both dry and humid conditions
2）Excellent thermal and chemical stability
3）Long operational lifespan with minimal degradation
4）No secondary pollution, as the reaction produces only oxygen
It is suitable for use in:
1）Industrial ozone exhaust treatment systems
2）Ozone sterilization and disinfection equipment
3）Semiconductor and electronics manufacturing facilities
4）Laboratory and cleanroom ventilation systems
5. Safety and Handling
The catalyst should be handled in accordance with the product’s Safety Data Sheet (SDS).
Use appropriate personal protective equipment (PPE) and store the catalyst in a cool, dry, sealed container away from incompatible materials such as acids, oxidizers, or combustible substances.
