Abstract A continuous flow fixed bed reactor was used to study the heterogeneous catalytic reaction ki-netics for dehydrogenation of cyclohexanol. The kinetic parameter of power velocity model was calculatedand the reaction's apparent activation energy Ea, was equal to 44. 28 kj/mol. The velocity-controlling mod-els were derived from self-equilibration method, and the model's parameter and the material's adsorptionenthalpy were calculated. The results showed that the models based on adsorption of cyclohexanol and sur-face reaction were correlated. The results of variance and residual error showed that the error was in therange of kinetic toleration, and the experiment did not have any system error. The velocity-controllingmodel based on surface reaction had a relatively minimal error.
