Professional Specifications and Application Guidelines by DEAI CHEM
Ozone is widely used in sterilization, oxidation, surface treatment, and advanced air-cleaning processes. However, residual ozone must be safely eliminated before treated air is discharged or before ozone-based equipment can be accessed. To address this essential requirement, DEAI CHEM provides a high-efficiency Ozone Destruct Catalyst, engineered to convert ozone (O₃) to oxygen (O₂) in a stable, non-consumptive catalytic process. Our material is used extensively in ozone destruct units, textile decontamination cabinets, industrial oxidation processes, and air-handling equipment requiring controlled ozone removal.
1. Functional Principle and Material Stability
DEAI CHEM Ozone Destruct Catalyst promotes the decomposition of ozone through a surface-driven catalytic mechanism. When ozone passes through the catalyst bed, it undergoes rapid conversion into oxygen without inducing structural breakdown of the catalyst. This means the material does not disintegrate, does not powder, and does not lose mechanical integrity under standard ozone exposure. The reaction proceeds efficiently at ambient temperatures, making it compatible with a wide range of industrial and laboratory systems.
2. Engineering Compatibility and Safety Requirements
Because the catalytic decomposition of ozone generates heat, the catalyst must be installed inside a stainless steel destruct chamber engineered to tolerate temperature rise and ensure uniform gas distribution. The use of PVC or other plastics is strongly discouraged as these materials can soften or ignite under elevated temperatures, creating a safety hazard.
The catalyst itself is non-hazardous. Spent catalyst material can be disposed of through regular landfill channels without special handling procedures, simplifying lifecycle management for industrial users.
3. Catalyst Lifespan and Contamination Considerations
Although the catalyst is not consumed by the reaction, exposure to certain contaminants will gradually inhibit its activity. Substances such as sulfur compounds, halogenated compounds, hydrocarbons, metal vapors, NOx, silica, and condensed water can poison or physically damage the catalyst surface. For this reason, DEAI CHEM recommends replacing the catalyst annually under standard operating conditions.
In applications with elevated humidity, the inlet air should be pre-heated approximately 9°C (15°F) above ambient temperature to prevent condensation inside the catalyst bed. Moisture accumulation is one of the fastest ways to compromise catalyst performance.
4. Physical Characteristics and Performance Specifications
DEAI CHEM Ozone Destruct Catalyst is supplied as a 4–8 mesh granular material with a uniform black to dark brown appearance. The granule size provides a balanced combination of low pressure drop and high effective contact surface. The catalyst has a bulk density in the range of 0.75 to 0.89 g/cc, offering stable packing characteristics for vertically oriented vessels.
A key performance attribute of this material is its high surface area, reaching 200 m²/g or higher, which supports efficient ozone decomposition under continuous-flow conditions. The catalyst is designed to maintain structural durability, ensuring consistent activity throughout its operational lifespan.
5. Recommended Operating Conditions
To achieve optimum destruction efficiency, DEAI CHEM recommends using a vertically oriented vessel with a top-down airflow configuration. Gas hourly space velocity should not exceed 5,000 hr⁻¹, and the linear gas velocity should be maintained at 0.66 m/sec (2.2 ft/sec) or higher. These engineering parameters help ensure uniform gas distribution and sustained catalytic performance.
In environments with measurable humidity, pre-heating the incoming air remains essential to prevent condensation from forming on the catalyst surface. No water, whether liquid or condensed, should be allowed to enter the catalyst bed.
6. Applications Across Industries
DEAI CHEM Ozone Destruct Catalyst is utilized by industrial and laboratory clients worldwide in:
• textile decontamination cabinets,
• industrial ozone generator exhaust systems,
• laboratory sterilization and safety cabinets,
• semiconductor clean-processing exhaust streams,
• water treatment ozone off-gas systems,
• closed-loop oxidation process equipment.
These fields require precise ozone control and rely on catalytic materials that are stable, predictable, and compliant with international engineering norms.
Conclusion
DEAI CHEM’s Ozone Destruct Catalyst offers a reliable, scientifically validated solution for industries that must ensure safe ozone elimination. Its stable catalytic characteristics, defined engineering requirements, and compatibility with global ozone destruction systems position it as a trusted material for ozone-to-oxygen conversion in critical environments.
