To be a valuable global supplier
for metallic honeycombs and turbine parts
In many industrial systems, metal substrate oxidation catalysts are essential for keeping emissions under control. They’re tough and built for high temperatures, but over time, carbon deposits, corrosion, and clogging can reduce their efficiency. Regular care is the simplest way to keep them working reliably.
1. Watch for Early Signs
Most problems show up gradually. A slight color change, unusual pressure drop, or slower gas flow often signals that the metal substrate oxidation catalysts are starting to lose performance. Regular visual inspections and basic monitoring can catch these early, saving bigger repairs later.
2. Deal With Carbon Deposits
Carbon buildup is common. Soot or leftover hydrocarbons can block the catalyst surface and reduce efficiency. Light deposits can usually be removed with air or steam cleaning. If the buildup is heavier, slow and controlled heating can restore performance. Sudden temperature changes should be avoided, as they can damage the metal structure.
3. Prevent Corrosion
Even though these catalysts are made of metal, corrosion can still occur, especially when moisture or sulfur compounds are present. Small corrosion spots should be addressed right away. Drying the system during downtime and applying protective coatings where necessary can prevent corrosion from spreading. Regular checks make sure the metal substrate oxidation catalysts remain structurally sound.
4. Keep the Channels Clear
Clogging in the channels reduces airflow and efficiency. Dust, ash, or small particles can settle in the honeycomb structure. Using upstream filters can help reduce debris. If clogging occurs, gentle cleaning methods like back-flushing with inert gas or ultrasonic cleaning can restore proper flow without harming the catalyst. Clear channels are key to keeping metal substrate oxidation catalysts effective over time.
5. Make a Routine Maintenance Plan
Consistency matters. Keeping track of temperature, pressure, and flow, along with regular cleaning and inspection, helps you notice wear patterns and plan regeneration before efficiency drops. Simple logs and hands-on checks often work better than relying on automated alerts alone.
Conclusion
Proper care extends the life of metal substrate oxidation catalysts and keeps them working efficiently. Regular checks, early cleaning, corrosion control, and unclogged channels make a big difference. Treat these catalysts as valuable equipment, and they’ll continue performing reliably for years.
