Engineered Control of Ozone, Carbon Monoxide, and VOC Emissions

 

 

In air pollution control, the selection of a catalyst is never a purely technical choice. It directly affects regulatory compliance, operational reliability, lifecycle cost, and long-term risk management. As global emission standards continue to tighten, industries dealing with ozone (O₃), carbon monoxide (CO), and volatile organic compounds (VOCs) require solutions that are not only effective, but verifiable, stable, and adaptable to real operating conditions.

 

As we move into 2026, DEAI CHEM continues to focus on application-driven catalyst design—delivering configurable, system-ready solutions that help industrial operators achieve consistent emission control under demanding environments.

 

 

 

 

Pollution Control Is Never One-Size-Fits-All

 

 

Industrial air treatment systems often operate under challenging conditions, including high humidity, fluctuating temperatures, limited installation space, and continuous duty cycles. Each pollutant presents a distinct technical and safety challenge that must be addressed with a targeted approach.

 

 

•Ozone (O₃)

Ozone is widely used for disinfection in water treatment and industrial processes. However, its strong oxidative nature and respiratory toxicity require that residual ozone be fully destroyed prior to venting. Uncontrolled ozone emissions pose both occupational safety risks and regulatory exposure.

 

 

•Carbon Monoxide (CO)

CO is commonly encountered in breathing air systems, cryogenic air separation units, and industrial exhaust streams. Colorless and odorless, it represents a serious life-safety hazard even at low concentrations, making reliable removal essential rather than optional.

 

 

•Volatile Organic Compounds (VOCs)

VOCs such as formaldehyde, alcohols, and other hydrocarbons are prevalent in both indoor air environments and industrial off-gas streams. Due to their health impacts and contribution to secondary ozone formation, VOC emissions are subject to increasing regulatory scrutiny.

 

 

Effective air pollution control therefore requires catalyst solutions designed specifically for the pollutant chemistry, operating conditions, and system constraints involved.

 

 

 

 

DEAI CHEM’s Catalyst Design Philosophy

 

 

Each DEAI CHEM catalyst is developed through years of field application experience and continuous refinement. Our design philosophy is built around three core principles:

 

• Clear targeting of specific pollutants

• Compatibility with real-world operating conditions

• Seamless integration into existing systems with minimal modification

 

 

1） Ozone Decomposition Catalyst

 

Designed specifically for ozone destruction, this catalyst is widely applied in ozone disinfection off-gas treatment for water utilities, laboratory exhaust systems, corona treaters, and non-thermal plasma processes.

It operates efficiently at ambient temperature without external heat input, catalytically converting ozone into oxygen with no secondary byproducts. The result is a passive, low-maintenance solution well suited for continuous operation.

 

 

2） CO Removal Catalyst

 

This catalyst is engineered for high-efficiency oxidation of carbon monoxide and is commonly deployed in industrial compressed air systems, cryogenic air separation units, personal respiratory protection equipment, aircraft cabins, and subsea breathing air systems.

It delivers high CO conversion activity at ambient or slightly elevated temperatures while maintaining minimal pressure drop—an essential requirement for safety-critical air supply applications.

 

 

3） Hopcalite Catalyst

 

Hopcalite Catalyst is a multifunctional material capable of addressing both ozone and selected VOCs, including formaldehyde, ethanol, and acetaldehyde.

Typically supplied in powder form, it can be coated onto metal, ceramic, or fiber-based substrates, enabling flexible integration into indoor air quality systems, cleanrooms, and consumer electronics-related applications where space efficiency and performance stability are critical.

 

 

 

 

Substrate Selection Defines System Performance

 

 

In practical applications, catalyst performance is inseparable from substrate selection. The choice of substrate directly influences pressure drop, gas residence time, and compatibility with existing equipment.

 

Powder catalysts offer maximum design flexibility and are commonly applied to a range of substrates. Metal honeycombs provide high durability, flame resistance, and low pressure drop. Cellulose foam structures offer high surface area for cost-sensitive applications, while nonwoven media are well suited for lightweight HVAC and air purification systems.

 

Granular catalysts are typically loaded into packed-bed reactors, filter cartridges, or gas scrubber canisters, making them ideal for continuous, high-throughput operations. When selecting a substrate, it is essential to consider resistance to corrosive gases, thermal stability, and available installation space to ensure long-term system reliability.

 

 

 

 

Proven Applications Across Industries

 

 

DEAI CHEM catalyst solutions are deployed across a broad range of validated industrial environments:

 

• Municipal water treatment facilities use ozone decomposition catalysts to safely neutralize disinfection off-gas prior to release

• Cryogenic air separation units rely on CO removal catalysts to protect sensitive downstream equipment

• Medical, firefighting, and mining rescue systems depend on consistent CO removal for breathing air safety

• Commercial, institutional, and residential environments utilize Hopcalite Catalyst to reduce formaldehyde and residual ozone, improving indoor air quality

 

These applications are supported by operational experience, not laboratory theory.

 

 

 

 

A Commitment Moving Into 2026

 

 

As we enter 2026, DEAI CHEM remains committed to delivering catalyst solutions defined by measurable performance, engineering practicality, and long-term reliability. Our ongoing development of Hopcalite Catalyst, Ozone Decomposition Catalyst, and CO Removal Catalyst reflects a single objective: to provide industrial partners with solutions that remain dependable long after installation.
