Kinetics on Hydrogenation of Cyclopentadiene over Pd/γ-Al2O3 Catalyst

The macrokinetics of hydrogenation of cyclopentadiene was investigated over Pd/γ-AlOcatalyst. Experimental results showed that the relationship between the constituents and reaction time was in agreement with the characteristic of consecutive irreversible first-order reaction.Analysis on the reaction mechanism of selective hydrogenation of cyclopentadiene indicated that it is reasonable to express the hydrogenation rate of cyclopentadiene in the power law form.Parameters of the kinetic model were obtained by the Gauss-Newton method based on the experimental data.From the statistic test and residual error distribution the kinetic model was proved to be adequate.
