Kinetics Study on Catalytic Dehydrogenation of Cyclohexanol

Abstract

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 E_a, 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.
