DNU

Umicore’s high performance CuSCR catalyst for Power Generation

State of the art Copper SCR catalyst

The Power Generation Industry’s need for energy is ever more demanding, driven by growing electricity needs and the accelerating power consumption of data centers. Securing reliable operation and efficient power output while keeping within environmental regulations is paramount. Umicore offers a unique and diversified program of coated catalysts for the Power Generation Industry. Our solutions include efficient removal of NOx, NH3, CO, VOC, N2O, and particulate removal. For high NOx efficiency using clean fuels at the lowest possible footprint, our DNU copper zeolite-based catalyst is the clear choice. Optimized for Back Up Diesel Engines and for continuous Power Natural Gas Engines especially for data center applications.

The 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
