High-performance NOâ‚“ reduction for low-dust applications
Umicore’s DNX LD (Low Dust) catalyst is designed for selective catalytic reduction (SCR) installations in low‑dust environments from metal sintering to heaters applications. Based on a fiber‑reinforced vanadium–tungsten–titania catalyst with a 0.3 - 0.4 mm wall, it is also suited for applications operating under controlled dust conditions, such as coal-fired boilers and waste to energy installations.
The catalyst design is tailored to operating requirements by adjusting activity, pitch size and wall thickness. This flexibility supports optimized performance across a wide range of applications and process conditions.
Proven through extensive industrial experience and testing, the DNX LD catalyst maintains activity over long operating periods. Its design supports stable operation, contributing to extended service life, low pressure drop and cost efficient system performance.
