Washcoating of MnOx on FeCralloy monoliths

摘要

Two MnOsubx/sub catalyst as powder, prepared by decomposition of two different MnCOsub3/sub, 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 gsup-1/sup and conversion msup-2/sup show that PM25 is the more active monolith.
