Waschcoating of MnOx on FeCralloy monoliths

Abstract

Two MnOx catalyst as powder, prepared by decomposition of two different MnCO3, have been deposited on a FeCrAlloy® metallic monolith by means of washcoating using slurry concentration of 25 and 40 wt(%) (PM25, PM40 and AM25). When increase slurry concentration increase the amount of deposited material, but lower adhesion of solid retained is observed. The obtained monoliths showed excellent catalytic activity in the combustion of ethyl acetate and toluene, being the monoliths activity order: PM40 > AM25 > PM25. Nevertheless, the conversion g-1 and conversion m-2 show that PM25 is the more active monolith.
