| Reliable CO Oxidation in Breathing Air and Industrial Gas Systems
Carbon monoxide (CO) remains one of the most critical trace contaminants in industrial and breathing air environments. Colorless, odorless, and highly toxic, CO poses immediate risks to personnel safety and can compromise sensitive downstream equipment in gas processing systems. Effective removal of carbon monoxide is therefore essential across compressed air networks, cryogenic air separation units, and life-support applications.
DEAI CHEM’s Hopcalite Catalyst is designed specifically for the catalytic oxidation of carbon monoxide at ambient or slightly elevated temperatures. Through a proven oxidation mechanism, CO is converted into carbon dioxide (CO₂), enabling reliable purification without the need for high-temperature operation.
| Operating Principle
Hopcalite functions as an oxidation catalyst. When carbon monoxide-containing air passes through a properly designed catalyst bed, CO reacts with oxygen over the active surface and is oxidized to CO₂.
Key operational characteristics include:
• Effective at ambient or moderately elevated temperatures
• No external heating required under normal operating conditions
• Continuous catalytic conversion when oxygen is present
• Suitable for dry or controlled-humidity air streams
This ambient-temperature performance makes Hopcalite particularly suitable for applications where thermal systems are impractical or energy-intensive.
| Typical Application Areas
1. Industrial Compressed Air Systems
Compressed air networks used in manufacturing facilities must meet strict purity standards. Trace CO contamination can arise from intake air pollution or compressor malfunction. Hopcalite catalyst beds provide an additional safety layer by ensuring carbon monoxide levels remain within acceptable limits before distribution.
2. Cryogenic Air Separation Units (ASU)
In cryogenic air separation, trace hydrocarbons and carbon monoxide must be removed upstream to protect cold box equipment and prevent operational hazards. Hopcalite catalysts are deployed in purification stages to eliminate CO prior to cryogenic processing, safeguarding downstream heat exchangers and distillation columns.
3. Breathing Air Systems
In compressed breathing air applications, carbon monoxide removal is critical for life safety. Hopcalite catalysts are used in:
• Hospital oxygen and medical air systems
• SCUBA and diving cylinders
• Firefighting and mine rescue respirators
• Aircraft cabin air support systems
• Subsea breathing air systems
In these environments, reliability and consistent oxidation performance are non-negotiable.
| Reactor and Deployment Configurations
Hopcalite Catalyst is typically supplied in granular form, allowing integration into:
• Packed bed reactors
• Filter cartridges
• Gas scrubber canisters
Powder forms are also available for specific engineered configurations where coating or customized media preparation is required.
The granular configuration enables predictable residence time control and uniform gas distribution when installed in properly designed housings.
| Technical Characteristics
• Target pollutant: Carbon Monoxide (CO)
• Operating temperature: Ambient or slightly elevated
• Form: Granular and powder
• Primary advantage: High catalytic activity for CO oxidation with minimal pressure drop
Low pressure drop is particularly important in breathing air systems and compressed air lines, where airflow resistance directly impacts energy consumption and operational efficiency.
| Design Considerations for System Integration
Successful carbon monoxide removal depends not only on catalyst selection, but also on proper system engineering. When specifying Hopcalite Catalyst, attention should be given to:
• Compatibility with corrosive or reactive gas components
• Humidity control, as excessive moisture can influence catalytic activity
• Operating temperature stability
• Available installation space and pressure drop limitations
Correct bed sizing, airflow management, and environmental control ensure consistent catalytic performance over time.
| A Critical Component in CO Risk Management
Carbon monoxide hazards cannot be detected by human senses. For this reason, engineered removal systems serve as a vital safeguard in both industrial and life-support environments.
DEAI CHEM’s Hopcalite Catalyst provides a dependable, ambient-temperature solution for carbon monoxide oxidation, supporting compliance, equipment protection, and human safety across demanding applications.
