Characterisation of palladium supported on exchanged BEA and FAU zeolites for VOCs catalytic oxidation

Résumé

0.5wt% palladium supported on exchanged BEA and FAU zeolites have been characterised for volatile organic compounds (VOCs) catalytic oxidation. BEA and FAU zeolites have been exchanged with different cations to study the influence of alkali metal cations (Na+, Cs+) and H+ in Pd based catalysts on propene total oxidation. Oxidation of propene depends significantly on the type of zeolites and on the compensating cation of the zeolite. According to sample, the catalytic activity is explained by the surface areas of the catalysts, the adsorption energies for VOC, the influence of the electronegativity of the compensating cation on the Pd particles, the Pd dispersion and the PdO reducibility.
