ANALYSIS OF PLATE-TYPE MONOLITH SCR-DENO(X) CATALYSTS

The performance of SCR commercial plate-type catalysts in the DeNO(x) reaction and in the oxidation of SO2 to SO3 was studied on a lab-scale by using the catalysts in the form of slabs: an extended experimental campaign and a kinetic analysis of the data resulted in the evaluatio n of the intrinsic activity, the role of the morphological properties and the effect of the geometry in the SCR process. Scale-up of the res ults was also addressed, this involved the estimate of external mass t ransfer coefficients for the complex channel geometry which characteri zes the industrial plate-type monoliths.
