Dual-function emission control for low-dust applications
Umicore’s DNO LD (Low Dust) catalysts are designed to deliver combined emission control and are specifically suited for selective catalytic reduction (SCR) installations in low-dust applications. These include boilers (gas- and oil-fired), cement and lime production, metal sintering and glass manufacturing. They are also applied in heaters, ethylene crackers, waste-to-energy plants and engines, supporting flexible integration across different industrial emission control systems.
Based on a fiber‑reinforced noble metal–vanadium–tungsten–titania formulation, they enable efficient carbon monoxide (CO) oxidation together with VOC and DeNOₓ activity, supporting reliable performance across varying operating conditions.
The DNO catalysts provide dual functionality by combining CO and VOC oxidation with SCR performance, allowing flexible positioning within the reactor. In combined DNX®–DNO configurations, this enables optimized system layouts and can reduce overall catalyst volume requirements.
The fiber‑reinforced design offers high resistance to thermal shock, allowing fast heat‑up and supporting rapid compliance during start-up conditions, while maintaining stable operation over time.
