NO reduction by CO over noble-metal catalysts under cycled feedstreams
The reduction of NO with CO was studied over ..cap alpha..-Al/sub 2/O/sub 3/-supported Pt, Pd, Rh, Ru, and Ir catalysts. The activities were measured by using cycled feeds and steady noncycled feed. The activity sequence of the catalysts tested was Rh > Ru > Ir > Pd > Pt. The activities of Pt and Pd catalysts were increased under the cycled feed. The periodic operation effect on the Pt catalyst was more predominant than that on the Pd catalyst. The order of periodic operation effect corresponded to the order of their susceptibility to CO self-poisoning.
