Abstract : This article reports the results obtained during the kinetic study of propene total oxidation on a platinum alumina catalyst in excess of oxygen. Reaction partial orders of propene and oxygen exhibited values of about -0.5 and +1, respectively. Propene presented a great inhibitory effect whereas an increase of oxygen concentration promoted the reaction. Based on TPD results, a Langmuir-Hinshelwood LH model considering propene to be adsorbed without dissociation was raised. A good agreement between experimental data and predicted results was observed. The value of the adsorption constants obtained confirmed that oxygen was more weakly adsorbed on the catalyst than propene. (c) 2013 Elsevier B.V. All rights reserved.
