Abstract :
Kinetic investigations on the hydrogenolysis of butyl butyrate to butanol over a commercial Cu/ZnO/Al2O3 catalyst were conducted. The catalytic measurements at atmospheric pressure showed that the rate of hydrogenolysis was approximately 0.67 order with respect to butyl butyrate and had a positive effect for hydrogen. The activation energy of this reaction was measured to be about 62 kJ/mol, and D2 isotope studies corroborated that the hydrogenolysis of butyl butyrate proceeds via dissociative adsorption of ester producing C3H7CO and C4H9O fragments. In addition, kinetic studies, interpreted by applying the basis of the Langmuir–Hinshelwood model, suggested that the rate-determining step involves the dissociative adsorption of butyl butyrate. Finally, the rate expression derived in this study provided precise and reasonable fitting results, and an activation energy close to the value obtained from the power law equation.
