SCR DeNOx catalyst DNX-series
The DNX-HD catalyst is a fiber reinforced Vanadium-Tungsten-Titania catalyst. The catalyst is available with a 0.8 mm wall.
The DNX-HD catalyst is suitable for operation in a high-dust environment, and is typically used in SCR installations on coal-fired boilers burning coal with high dust content. The cell density (CPSI) is selected to accommodate the dust content in the flue gas.
The low weight of the DNX® catalyst results in a very low SO2-oxidation, which is further optimized by balancing the vanadium content in the catalyst versus the operating temperature. The tri-modal pore structure offers a high poison resistance and a low ABS dew point. Due to the fiber-reinforced carrier it has a high mechanical durability and is very thermal shock resistant which allows fast load changes of the boiler.
