SCR DeNOx catalyst DNX-series

DNX-HD

The DNX-HD catalyst is a fiber reinforced Vanadium-Tungsten-Titania catalyst. The catalyst is available with a 0.8 mm wall.

Application areas

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.

Features and Values

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.
