A Cost-Effective Solution for Low-Temperature CO Catalytic Oxidation

Industrial carbon monoxide (CO) emissions can be efficiently converted into harmless carbon dioxide (CO₂) through catalytic oxidation technology. Compared with high-temperature thermal oxidation and conventional precious metal catalysts, manganese-based carbon monoxide catalysts achieve efficient CO removal at much lower operating temperatures while reducing equipment investment, operating costs, and long-term maintenance expenses. For applications such as underground parking garages, industrial exhaust systems, air separation units, mining safety, and air purification, high-activity manganese-based catalysts offer an excellent balance between performance and cost-effectiveness. MINSTRONG MINSLITE-A is a high-performance CO oxidation catalyst developed based on this technology, designed to meet a wide range of industrial carbon monoxide removal requirements.

Why Do Industrial Facilities Need Carbon Monoxide Treatment?

Carbon monoxide (CO) is a colorless, odorless, and toxic gas primarily generated from incomplete combustion and certain industrial chemical processes. It is commonly found in boiler systems, industrial furnaces, waste incineration plants, air separation units, underground parking garages, mining operations, and chemical manufacturing facilities.

Because CO readily binds with hemoglobin in human blood, it significantly reduces oxygen transport capacity, posing serious health risks even at relatively low concentrations. Meanwhile, increasingly stringent environmental regulations worldwide require industries to reduce CO emissions. Therefore, installing an efficient, reliable, and economical carbon monoxide treatment system helps companies comply with emission standards while improving workplace safety.

Principle of Carbon Monoxide Catalytic Oxidation

Carbon monoxide catalytic oxidation utilizes active sites on the catalyst surface to accelerate the reaction between CO and oxygen:

2CO + O₂ → 2CO₂

The catalyst itself is not consumed during the reaction. Instead, it continuously provides active oxygen species and facilitates electron transfer, significantly accelerating the oxidation process.

Higher catalyst activity enables efficient CO conversion at lower temperatures, reducing both energy consumption and equipment investment. Therefore, low-temperature, highly active catalysts have become a major development direction for industrial CO treatment.

Comparison of Main CO Treatment Technologies

Technology	Operating Temperature	Energy Consumption	Initial Investment	Operating Cost	Typical Applications
Thermal Oxidation	>580°C	Very High	High	High	High-concentration exhaust gases
Precious Metal Catalysts	150–300°C	Medium	High	Medium	Fine chemicals, automotive exhaust
Manganese-Based Catalytic Oxidation (MINSLITE-A)	Room Temperature–150°C*	Low	Low	Low	Industrial exhaust, air purification, parking garages, mining

*Actual operating temperature depends on process conditions.

Compared with thermal oxidation, manganese-based catalytic oxidation eliminates the need for continuous high-temperature heating, significantly reducing energy consumption and capital investment. Compared with precious metal catalysts, manganese oxide catalysts utilize abundant transition metal oxides as active components, offering lower material costs while maintaining excellent catalytic performance.

Why Does MINSLITE-A Deliver Excellent Cost Performance?

MINSTRONG MINSLITE-A adopts an advanced manganese-based mixed oxide catalytic system. Through optimized active component ratios and manufacturing technology, it delivers excellent CO oxidation activity even at relatively low temperatures.

• Excellent low-temperature startup performance.
• Highly active surface structure for improved CO and oxygen contact.
• Lower material cost than precious metal catalysts.

• Suitable for long-term continuous industrial operation.

For industrial systems operating around the clock, reduced energy consumption and extended service life significantly lower total lifecycle costs.

Technical Features of MINSLITE-A

The outstanding catalytic performance of MINSLITE-A originates from its nano-scale porous structure combined with a highly active manganese oxide system.

The catalyst possesses a large specific surface area that provides abundant active reaction sites. As CO contacts the catalyst surface, it rapidly reacts with adsorbed oxygen to form CO₂. Meanwhile, the catalyst continuously regenerates active oxygen through redox cycling, enabling continuous catalytic oxidation.

By optimizing crystal lattice structure and oxygen vacancy distribution, MINSLITE-A enhances oxygen activation efficiency, significantly improving low-temperature catalytic performance.

The catalyst is available in various configurations, including pellets, cylinders, and honeycomb structures, allowing flexible reactor design while balancing catalytic efficiency, pressure drop, and catalyst loading.

Different catalyst structures—including honeycomb and pellet types—can be selected according to airflow rate, pressure drop, and equipment configuration.

Important Operating Considerations

1. Control Moisture

High humidity may temporarily affect catalyst surface activity. Liquid water should be prevented from entering the catalyst bed. For high-humidity applications, preheating or dehumidification is recommended.

2. Prevent Catalyst Poisoning

Sulfur-, phosphorus-, silicon-, and halogen-containing compounds may reduce catalyst activity. Appropriate pretreatment systems should be installed whenever these contaminants are present.

3. Optimize Gas Space Velocity

Excessively high GHSV shortens gas residence time and may reduce removal efficiency, while excessively low GHSV increases equipment size. Proper reactor design optimizes both efficiency and investment cost.

4. Perform Routine System Inspection

Regular monitoring of pressure drop, CO concentration, and catalyst performance helps identify abnormal operating conditions and extends catalyst service life.

How to Select the Right Carbon Monoxide Catalyst

When selecting a CO oxidation catalyst, engineers should evaluate:

• CO concentration
• Exhaust gas temperature
• Humidity level
• Sulfur, chlorine, silicon, and other contaminants
• Airflow rate
• Emission requirements
• Operating costs
• Catalyst lifetime and maintenance intervals

Proper catalyst selection combined with optimized reactor design delivers superior treatment efficiency and long-term economic performance.
