SCR Catalysts(Fe-BEA Zeolite High temperature)

Description

1.The high temperature iron-based molecular sieve scr catalyst system has the advantages of wide temperature window, good high temperature stability, high purification efficiency, and non-toxicity. Its performance is significantly better than that of the V2O5/WO3/TiO2 catalyst. It remains excellent after aging at 670℃ for 64 hours. Purification performance is the mainstream catalyst for NOx purification of diesel engines.

2. Fe-based molecular sieve SCR-sulfur and high temperature resistance, good durability, wide temperature window, suitable for heavy-duty diesel vehicles and truck engineering vehicles that do not require high oil quality, and can be matched with DOC to reduce the ignition temperature.

3. Cu-based molecular sieve SCR-low temperature and high conversion, excellent ammonia storage performance, suitable for city buses and buses with good oil products.

4. Cu﹠Fe composite molecular sieve SCR-low ignition temperature, wide temperature window, good durability, and both Cu-based and Fe-based performance.
