The DNX-FCC catalyst – Medium dust applications
Haldor Topsoe DNX®FCC-series of catalysts is especially developed and optimized for FCC units. It has a pitch that is carefully selected to ensure a smooth operation both during normal operation and during off-sets situations with very high dust content sometimes experienced on FCC units.
The wall thickness is optimized to ensure a very high DeNOx activity in combination with reduced pressure drop and SO2 oxidation while still ensuring a with a high mechanical strength.
The FCC catalyst comes in a variety of vanadium concentrations and pitch sizes to guarantee optimal performance for any application or industry.
The design and manufacture of Topsoe’s DNX catalysts are based on a solid fundamental understanding of surface physics and chemistry to ensure high activity while keeping the SO2 oxidation at a minimum.
All types of fuels and industries
The FCC catalyst series are especially developed for FCC units, but can be applied in a range of fuels like biomass, cement, waste, and glass furnace. The FCC catalyst can be designed to meet the exact operating condition by varying the active parts of the catalyst and the pitch sizes to meet the requested performance.
Very stable activity
Our industrial experiences 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. Topsoe is capable of tailor-making catalysts for any application and for any level of dust, sulfur in the fuel or poisons in the fuel and can therefore provide the best performance in terms of NOx removal, pressure drop and lifetime of the catalyst.
The exceptional combination of the above features of the DNX®FCC catalysts 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.
