DNA – Ammonia Oxidation Catalyst

Ammonia is crucial for reducing NOx emissions through SCR technology and is widely used in various chemical processes. However, while it will also play an important role as a carbon-free, climate-friendly fuel for internal combustion engines and power generation, the toxic properties of ammonia are an increasing concern for legislators, environmental organizations, and consumers.

To address this, Umicore offers a unique catalyst technology for an efficient and cost-effective abatement of ammonia emissions.

The benefits of DNA

• Highly selective oxidation of ammonia
• Additional capability for CO and VOC removal
• Wide range of design temperature from 480-1020 °F (250- 550 °C)
• Low pressure drop
• Local manufacturing through Umicore’s global production footprint

Application areas

• Diesel engines – avoid ammonia slip in applications with high NOx reduction
• Ammonia-fueled engines and boilers – reduce unburnt fuel residues
• Industrial processes – knock down ammonia in the off-gas
