AGING OF PELLETED AND MONOLITHIC AUTOMOTIVE EMISSION CONTROL CATALYSTS 800842

Experimental dual bed pelleted and monolithic automotive emission control catalysts were prepared and aged on an engine-dynamometer under identical conditions. The catalysts contained the same noble metal loadings and had the same noble metal ratios.
The warmed-up conversion performance was obtained for both the front bed catalyst only and for the two catalyst beds in combination. The contaminant pickups and penetrations into the pellets were also measured.
