SCR DeNOx catalyst DNX-series
The DNX-GT catalyst is a fiber reinforced Vanadium-Tungsten-Titania catalyst especially optimized for gas turbine applications. The DNX-GT series offers a very high activity in combination with low pressure drop. The catalyst is available with a 0.3 mm wall.
The DNX-GT catalysts are typically operating on gas turbines.
The DNX-GT catalysts feature an enhanced SCR activity which has been achieved through reformulating and changing the monolith structure of the original DNX® catalyst. Thereby an increased specific surface area and a higher catalyst wall utilization have been achieved which together with a larger open area provide an attractive combination of increased activity and lower pressure drop.
The 20% boost in volume activity for the DNX-GT catalysts yield a corresponding reduction in required catalyst volume. Together with a 10% lower specific pressure drop, the DNX-GT catalysts offer a saving in overall pressure loss across the SCR catalyst in the order of 30% compared to the previous DNX® versions.
Due to the low weight it heats up fast during start-up and is therefore also fast to be in compliance.
