SCR DeNOx/Oxidation catalyst DNO-series
The DNO-FCC catalyst is a fiber reinforced Noble Metal-Vanadium-Tungsten-Titania catalyst. The DNO-series offers a very high CO oxidation activity in combination with a moderate to high VOC and DeNOx activity (both temperature dependent).
The DNO-FCC catalysts are especially suited for SCR installations on FCC units.
The DNO catalysts benefit from a dual functionality as the catalysts pose an activity for CO and VOC oxidation in addition to the SCR activity. The DNO catalysts share the features of the well-proven DNX® catalyst.
The dual funtionality of the DNO catalyst makes it possible just to replace the lower DNX® layer in the SCR reactor where the DNO removes the CO typically experienced during low load operation of the FCC unit.
The fiber-reinforced catalyst is very thermal shock resistant which allows a fast heat up rate. Hence the unit will be fast to be in compliance.
