Catalytic oxidation effectively removes harmful substances and compounds from almost all exhaust gas streams at relatively low temperatures. Due to the low operating temperature, a catalytic converter significantly reduces energy consumption and therefore reduces the environmental impact even further.
The exhaust gas from the production process is first drawn in via the integrated fan, passed through a heat recovery unit and preheated with the hot clean gas from the ACP. This preheated exhaust gas is then heated further to the required inlet temperature with the aid of a preferably electric heater before it enters the catalytic converter.
The required temperature depends mainly on the substances to be decomposed. The catalyst usually consists of precious metals or metal oxides, which accelerate the oxidation of the pollutants and allow them to completely decompose at lower temperatures. This leads to significantly higher energy efficiency.
Finally, the purified exhaust air is led outside via the heat recovery unit. The waste heat recovered in the process is used further in the cycle and serves to preheat the cold raw gas. This contributes to a further improvement in energy efficiency.

Catalysts for the removal of volatile organic compounds (VOC)
Catalytic oxidation is widely considered to be the most effective method of reducing VOC emissions.
The xpuriCAT Oxi catalyst series enables catalytic combustion at lower temperatures, reducing operating costs and minimizing thermal and mechanical stress on equipment. This process includes the oxidation of CO and various hydrocarbons - such as formaldehyde, aldehydes, PAHs, NMHCs, VOCs and TOCs - to harmless CO2 and water.

Purification of technical gases
The xpuriCAT Pure catalyst series is used for gas purification of trace pollutants, including VOCs, O2 and H2. These catalysts are effective in purifying a range of technical gases such as methane (CH4), argon (Ar), helium (He), nitrogen (N2), oxygen (O2), hydrogen (H2) and carbon dioxide (CO2). xpuriCAT Pure catalysts are ideal for industries that require deoxygenation (DeOxo) and general gas purification, such as electrolysis, biogas, pipeline gas, beverages, landfills and semiconductor manufacturing.

Removal of nitrous oxide (N2O) and ammonia (NH3)
The removal of gaseous ammonia NH3 or nitrous oxide N2O is no easy task. Nitrous oxide is a powerful greenhouse gas with a global warming potential almost 300 times that of CO2. Our N2O degradation catalysts offer a cost-effective solution that is significantly lower than standard CO2 prices. The removal of gaseous ammonia is a tricky business, where our catalyst offers extremely high efficiency combined with high selectivity for harmless nitrogen (N2).
