Oxidation of toluene to benzaldehyde over VSb1-xTixO4 catalyst. Kinetics studies
In this work a kinetic study of the vapor phase oxidation of toluene by air using titanium doped vanadium antimonate as catalytic system, is reported. The catalytic tests were performed in an integral fixed-bed reactor operating at atmospheric pressure. From the results obtained in the introductory...

| 520 | 3 | |a In this work a kinetic study of the vapor phase oxidation of toluene by air using titanium doped vanadium antimonate as catalytic system, is reported. The catalytic tests were performed in an integral fixed-bed reactor operating at atmospheric pressure. From the results obtained in the introductory kinetic tests, a kinetic scheme that considers the partial oxidation of toluene to benzaldehyde, a consecutive oxidation of benzaldehyde to carbon oxides and a parallel oxidation of toluene to carbon oxides, is proposed. The corresponding kinetic parameters are estimated using non-linear regression. There is a good fitting between the regression curves and the experimental data. The oxidation of toluene takes place on a partially reduced catalyst surface. The overall rate depends on the partial pressures of the reactants. The three steps of the kinetic mechanism have similar activation energies indicating that the same intermediate is involved. In the range of the operating conditions, there is no rate-controlling step. © 2000 Elsevier Science B. V. All rights reserved. |l eng | |
