Ozone (O₃) is widely applied across industrial and municipal processes due to its strong oxidizing capability, particularly in water disinfection, air treatment, and surface sterilization. However, residual ozone released in exhaust streams presents a well-documented risk to human health and the environment. Effective destruction of ozone prior to discharge is therefore a critical requirement in modern process design.
DEAI CHEM’s Ozone Decomposition Catalyst is engineered to address this requirement through a stable, passive catalytic solution that converts ozone into oxygen under ambient operating conditions.
Catalyst Composition and Design Philosophy
The Ozone Decomposition Catalyst developed by DEAI CHEM is primarily based on a controlled formulation of copper oxides and manganese oxides. This composition is widely recognized in catalytic oxidation systems for its ability to promote rapid ozone decomposition without structural degradation of the catalyst itself.
The catalyst is supplied in granular form, optimized for use in fixed-bed and cartridge-based ozone destruct systems. Particle size distribution and surface characteristics are carefully controlled to balance high catalytic activity with acceptable pressure drop, ensuring suitability for continuous industrial operation.
Operating Principle
The catalyst functions through a surface-mediated reaction in which ozone molecules are adsorbed and decomposed into molecular oxygen. This process occurs spontaneously at ambient temperature and does not require external heat input or electrical energy.
As ozone-laden air passes through the catalyst bed, ozone is converted directly into oxygen without generating secondary pollutants or reaction byproducts. This makes the catalyst particularly suitable for installations where thermal treatment or chemical scrubbing is impractical or undesirable.
Typical Application Scenarios
DEAI CHEM’s Ozone Decomposition Catalyst is designed for use in a broad range of exhaust gas treatment systems, including:
• Off-gas treatment from ozone-based water disinfection systems
• Laboratory exhaust streams containing residual ozone
• Corona discharge equipment used in surface treatment processes
• Non-thermal plasma and advanced oxidation systems where ozone is generated as a byproduct
In these applications, the catalyst serves as a final control stage, ensuring ozone concentrations are reduced to levels safe for release or downstream handling.
Key Performance Advantages
The catalyst offers several practical advantages for system designers and operators:
• Effective ozone destruction at ambient temperature, eliminating the need for heaters
• Stable catalytic activity during continuous operation
• No formation of secondary pollutants or hazardous residues
• Compatibility with stainless steel and ozone-resistant system materials
These characteristics contribute to simplified system design, reduced energy consumption, and lower overall operating costs.
Integration into Ozone Destruct Systems
For optimal performance, the catalyst should be installed in a properly designed vessel or housing that ensures uniform gas distribution and sufficient residence time. While the catalyst itself requires minimal maintenance, system design must account for moisture control and avoidance of contaminant species that could reduce catalytic activity over time.
DEAI CHEM provides technical support to assist customers in selecting appropriate catalyst grades and integration methods based on specific operating conditions and application requirements.
Conclusion
DEAI CHEM’s Ozone Decomposition Catalyst provides a reliable and efficient solution for controlling ozone emissions across a wide range of industrial and environmental applications. By combining proven catalytic chemistry with controlled manufacturing and application-focused design, the catalyst supports regulatory compliance, operational safety, and long-term system reliability.
