High-performance emission control catalysts for power generation
Umicore’s DNU catalyst offers a unique and diversified program of coated catalysts for the power generation industry – including efficient removal of NOx, NH3, CO, VOC, N2O, and particulate removal.
Our copper-based selective catalytic reduction (SCR) solution is the clear choice for the efficient removal of nitrogen oxides (NOₓ) across a wide temperature window while supporting reliable operation. Based on a copper zeolite formulation and proprietary coating technology, the DNU CuSCR catalyst delivers high activity with reduced catalyst volume compared to conventional SCR systems. This supports compact system design and efficient integration in applications such as backup diesel and natural gas engines, including data center power systems.
Key benefits of DNU
- Excellent low- and high-temperature NOx conversion
- Lowest catalyst volume possible (≥ 30% lower vs. V-SCR)
- Short lead times and supply from multiple global production plants
- Umicore’s proprietary coating of ceramic substrates
- Tungsten- and titanium-free technology, limiting reliance on materials affected by geopolitical pressures
System Design & Integration
- Design temperatures from 350 °F to 1160 °F (175 °C to 625 °C)
- Available geometries:
- Round: 10.5” x 6-12” depth - 300/5, 400/4 cpsi
- Square: 150 x 150 x 50-250mm - 230/8, 270/6 cpsi
- DNU can be combined with Umicore’s other catalyst technologies depending on fuel type and conditions:
- cDPF + DNU for : Particles & CO/VOC Oxidation + NOx
- DNU + DNA for : NOx + Ammonia Slip
- DOX + DNU for : CO/VOC Oxidation + NOx
