Proven Chemistry for Reliable Ozone Destruction
Ozone is widely applied in water treatment, disinfection, and industrial processing due to its strong oxidizing capability. However, residual ozone in off-gas streams presents significant health and environmental risks and must be reliably eliminated before release. DEAI CHEM’s Ozone Decomposition Catalyst, based on a manganese dioxide–copper oxide (MnO₂–CuO) formulation, is engineered to address this challenge with high efficiency, stability, and long-term reliability.
Catalyst Composition and Physical Characteristics
At the core of DEAI CHEM’s ozone decomposition technology is a carefully controlled mixed metal oxide system. The catalyst consists of manganese dioxide and copper oxide in a weight ratio optimized for ozone conversion efficiency and durability, typically within the range of 60–80% MnO₂ and 40–20% CuO. This composition leverages the complementary redox properties of both oxides, enabling rapid ozone decomposition without structural degradation of the catalyst.
The catalyst is supplied as a granular material with a bulk density ranging from 0.72 to 0.92 g/ml and a BET specific surface area exceeding 200 m²/g. The high surface area provides abundant active sites for ozone interaction, while the controlled bulk density supports predictable pressure drop behavior in fixed-bed systems. Visually, the material appears black to dark brown, consistent with high-purity mixed metal oxide catalysts. Standard particle sizes include 4 × 8 mesh and 8 × 14 mesh, allowing flexibility in reactor and cartridge design.
Mechanism of Ozone Decomposition
In a properly engineered ozone destruct system, DEAI CHEM’s MnO₂–CuO catalyst promotes the rapid decomposition of ozone into molecular oxygen at ambient temperature. No external heat source or additional reagents are required. As ozone-laden air passes through the catalyst bed, ozone molecules interact with the catalyst surface and undergo catalytic breakdown, releasing oxygen while leaving the catalyst chemically intact.
This true catalytic behavior differentiates the material from consumable media or adsorption-based solutions. The catalyst does not rely on chemical consumption and maintains its structural integrity under continuous operation when protected from known catalyst poisons.
Key Advantages of MnO₂–CuO Catalyst Systems
The manganese dioxide–copper oxide formulation offers several advantages that make it particularly well suited for industrial and municipal ozone destruction applications. It operates effectively at ambient temperature, simplifying system design and reducing energy consumption. The catalyst converts ozone exclusively to oxygen, producing no secondary byproducts that could complicate downstream compliance or maintenance.
The granular form allows easy integration into packed-bed reactors, filter housings, and gas treatment canisters. Combined with high surface area and mechanical stability, this enables consistent performance across a wide range of flow rates and ozone concentrations.
Application Scope
DEAI CHEM’s Ozone Decomposition Catalyst is widely deployed in off-gas treatment systems where ozone must be neutralized prior to venting. Typical applications include potable water and wastewater treatment facilities, where ozone is used for disinfection, as well as corona treater exhausts in packaging and film processing. The catalyst is also applied in office equipment emissions, laboratory exhaust systems, and chemical processing operations where ozone is generated as a byproduct.
In each of these environments, the catalyst provides a passive, low-maintenance solution for ozone control, supporting both regulatory compliance and occupational safety.
