Abstract
Kinetic measurement for the hydrogenolysis of butyl butyrate to butanol over a commercial Cu/ZnO/Al2O3 catalyst was conducted. From D2 isotope study, it was found that the hydrogenolysis of butyl butyrate proceeds via its dissociative adsorption producing C3H7CO and C4H9O fragments. Kinetic study, interpreted by applying the basis of the Langmuir-Hinshelwood model, suggested that the rate determining step involves the dissociative adsorption of butyl butyrate. In addition, Cu/ZnO/Al2O3 catalysts with different Cu/Zn ratios were prepared, characterized by XRD, TPR, TPO, and N2O titration, and tested for this reaction, showing that the catalyst with the Cu/Zn ratio of 5/1 showed the highest butanol formation rate.
