heal.abstract	Kinetic studies of acetaldehyde oxidation over Pt/Rh and Pd monolithic automotive catalysts were performed in a spinning-basket flow reactor under atmospheric pressure. The reaction temperature was varied between 350 and 570 K, while the acetaldehyde concentration ranged from 50 to 700 ppm and the oxygen concentration from 2.0 to 10.0% v/v. Among the kinetic models used in the analysis of the experimental data obtained in this work, the one accounting for the surface reaction between adsorbed oxygen and adsorbed reactant was valid for the oxidation over Pt/Rh. As regards the acetaldehyde oxidation over Pd, the kinetic model involving the surface reaction between dissociatively adsorbed reactants was found to yield the most successful fit. According to these models, the activation energy of acetaldehyde oxidation is estimated as 13 150 cal mol(-1) over Pt/Rh and 7500 cal mol(-1) over Pd catalyst.	en
