How a Catalytic Oxidizer Works

Catalytic oxidizers, also known as catalytic incinerators, are oxidation systems, similar to thermal oxidizers, that control VOC and volatile HAP emissions. This video explains more in detail about how they work.

These systems are most appropriately used in process applications that have lower concentrations of Volatile Organic Compounds (VOCs).

Catalytic oxidizers are capable of maintaining continuous steady-state operating conditions for nearly indefinite periods. First, the process air enters the oxidizer chamber and is heated before it passes through the catalyst. The air is heated to the appropriate catalyst activation temperature which varies, depending on the VOC and type of catalyst, and can range from 350 F to 650 F. Then, the process air first enters the heat exchanger and is pre-heated using the oxidizer’s exhaust energy prior to entering the oxidizer chamber.

Catalytic oxidizers are an excellent air pollution control option in applications that need to treat low VOC process streams. Compared to other pollution control technologies they are very cost-effective, exceptionally reliable, have a low impact on the manufacturing process, and generate less NOx and CO.
