A. Beretta et al., ANALYSIS OF THE PERFORMANCE OF PLATE-TYPE MONOLITHIC CATALYSTS FOR SELECTIVE CATALYTIC REDUCTION DENO(X) APPLICATIONS, Industrial & engineering chemistry research, 37(7), 1998, pp. 2623-2633
An approach to the analysis of the plate-type catalysts for high-dust
selective catalytic reduction (SCR) applications is herein presented.
Commercial systems were studied in the form of slabs. NOx reduction an
d SO2 oxidation runs were performed spanning a wide range of operating
conditions. The results were analyzed on the basis of a 1D model. The
estimates of the intrinsic activity parameters and of the effectivene
ss factors were found to differ significantly among the catalysts unde
r study. Aspects related to scale-up were also addressed on a prelimin
ary basis. Concerning the SO2 oxidation reaction, the lab-scale analys
is of the catalysts can be directly exploited for reactor design. On t
he contrary, the evaluation of the DeNO(x) performance of the industri
al plate-type monolith requires the study of the interphase mass trans
fer in the real scale; the NO conversion data collected in the slab-re
actor were estimated as not conservative in relation to design applica
tions.
