Manufacturer profiles associated with Active Catalytic Material.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The active catalytic material facilitates the chemical reduction of nitrogen oxides (NOx) to nitrogen and water using ammonia as a reducing agent, enabling compliance with emission regulations.
Optimal performance occurs between 300-400°C. Below this range, reaction kinetics slow; above this range, thermal degradation and ammonia oxidation may occur, reducing efficiency.
Common deactivation includes poisoning by sulfur compounds, fouling by particulate matter, thermal sintering at high temperatures, and chemical poisoning from alkali metals or phosphorus.
