Catalytic Oxidation

Catalytic oxidation systems

Catalytically supported oxidation enables the complete oxidation of VOCs from a temperature of just approximately 320°C. This means that exhaust air streams are cleaned extremely energy-efficiently and, compared to other thermal processes, enables savings in energy costs and CO2 emissions.

The systems are equipped as standard with a natural-gas burner or an electric air heater and thus offer extreme flexibility in application. An efficient heat exchanger enables the recovery of the process’s own heat. From a pollutant concentration of about 3 gC/Nm³, this enables autothermal operation – in the ideal case no additional energy is required for VOC oxidation.

The catalyst must be protected against dust and so-called “catalyst poisons” in order to avoid premature deactivation of the cleaning performance. A holistic assessment of the pollutants contained in the exhaust air is therefore required.

The process is based on lowering the activation energy for the oxidation of solvents through the use of a catalyst material such as platinum or palladium.
