Catalytic RTO (RCO) Systems

Catalytic RTO, also known as Regenerative Catalytic Oxidizer (RCO), is designed to oxidize VOCs at lower operating temperatures by integrating catalytic oxidation with regenerative heat recovery technology. This system significantly reduces fuel consumption while maintaining stable VOC destruction efficiency.

What Is Catalytic RTO (RCO)?

Catalytic RTO (RCO) combines regenerative thermal oxidation with catalytic oxidation. By using catalysts, VOCs are oxidized at significantly lower temperatures compared to conventional RTO systems.

This design makes RCO systems particularly suitable for low to medium VOC concentrations where energy efficiency and fuel cost reduction are critical.

System Design & Working Principle

• VOC-laden exhaust is preheated through ceramic heat storage beds
• Preheated gas passes through catalytic reactor
• Oxidation occurs at reduced temperature due to catalyst activity
• Clean exhaust transfers heat back to ceramic media
• Automatic valve switching ensures continuous operation

The lower oxidation temperature reduces auxiliary fuel demand and thermal stress on system components.
