SCR DeNOx catalyst DNX-series


The DNX-FCC catalyst is a fiber reinforced Vanadium-Tungsten-Titania catalyst. The catalyst is available in version with 0.6 mm wall. 

Application areas

The DNX-FCC catalyst is suitable for operation in a high-dust environment and it is typically used in SCR installations on FCC units. The cell density (CPSI) is selected to accommodate the specific dust content of the gas.  

Features and Values

The FCC catalyst can be optimized to meet the specific operating condition by varying the active constituents of the catalyst and the pitch size to meet the requested performance.

Our industrial experience together with the extensive testing in our laboratories have proven the FCC catalyst activity is maintained over long operation in a wide range of applications.

The exceptional combination of the above features of the DNX-FCC catalyst ensures a long trouble-free service life. This translates directly into minimized catalyst and operating costs and thus it ensures excellent value and easy operation.
