DEAI CHEM’s 4×8 mesh Ozone Decomposition Catalyst is a high-efficiency catalytic material designed to safely and effectively convert harmful ozone (O₃) into oxygen (O₂) across a wide range of industrial and environmental applications. Formulated from a balanced combination of manganese dioxide (MnO₂) and copper oxide (CuO), this catalyst offers reliable performance, long service life, and exceptional stability under challenging operating conditions.
Product Characteristics
The 4×8 mesh catalyst is characterized by its black to dark brown granular appearance and optimized physical properties that ensure effective ozone destruction:
MnO₂:CuO (weight ratio): 60–80% : 40–20%
Bulk Density: 0.72–0.92 g/mL
Tap Density: 0.79–1.00 g/mL
Specific Surface Area: ＞ 200 m²/g
Weight Loss: < 1%
Its high surface area and robust structure provide abundant active sites for ozone decomposition while maintaining structural integrity and performance stability over extended operational periods.
Recommended Operating Conditions
For maximum efficiency and catalyst longevity, it is essential to adhere to proper system design and operating parameters. The following conditions are recommended when integrating DEAI CHEM’s 4×8 mesh ozone decomposition catalyst into a destruct system:
1. System Compatibility: All construction materials in contact with ozone must be ozone-resistant to ensure safety and prevent material degradation.
2. Gas Hourly Space Velocity: ≤ 5,000 hr⁻¹ — ensures sufficient contact time between the gas and catalyst surface for complete ozone conversion.
3. Linear Velocity: ≥ 0.66 m/sec (2.2 ft/sec) — promotes optimal airflow and prevents channeling within the catalyst bed.
4. Humidity Control: In humid environments, pre-heat the gas stream to approximately 9 °C (15 °F) above ambient temperature before it enters the catalyst bed. This prevents moisture condensation on the catalyst surface, which can inhibit catalytic activity and reduce performance.
Additionally, a vertically oriented vessel with top-down airflow is recommended to maximize gas-catalyst contact and maintain consistent performance.
Applications Across Industries
The versatility of DEAI CHEM’s 4×8 mesh ozone decomposition catalyst makes it an essential solution in a variety of ozone-producing industrial processes. Its ability to efficiently convert harmful ozone into oxygen contributes to safer operations, improved air quality, and regulatory compliance. Key application areas include:
