Abstract

The reactions of propane with O2, N2O and NO over Pt, Pd and Rh catalysts have been investigated under near-stoichiometric conditions. In general, Pt is the most active catalyst for propane oxidation, followed by Pd and Rh. In individual tests, the reactivity of the oxidants varies widely, the order being O2 >> N2O > NO for Pt, O2 ≈ N2O >> NO for Rh, and N2O >> NO or O2 for Pd, where the reaction involving O2 is dependent on pretreatment and history. Interactions between oxidants alter the behaviour when all three are present. The order of reactivity changes to O2 > NO > N2O for Pt, O2 > N2O > NO for Rh, and O2 > NO > N2O for Pd. The findings imply substantial competition between oxidants, especially with Pt and Pd.
