Reduction of NO by CO over alumina-supported palladium catalyst
The kinetics of NO reduction by CO have been investigated over a Pd/Al/sub 2/O/sub 3/ catalyst. These studies have been complemented by pulse reaction, transient response method, and TPD. The performance of the Pd catalyst depended strongly on the ratio of NO/CO and the reaction temperature. It was shown that the N/sub 2/O selectivity was minimum at the stoichiometric ratio of NO/CO. For NO conversion below 20% at 350/sup 0/C, the kinetics for NO reduction and N/sub 2/ and N/sub 2/O formation over Pd catalysts were first order in NO and inverse first order in CO. The kinetics and product selectivity were found to be in good agreement with a mechanism based on the chemisorption of NO as the rate-limiting step.
