Ru/Al2O3 catalyst is prepared through using the equivalent volumetric impregnation method,and the kinetics of bisphenol A hydrogenation over the catalyst is studied in a batch reactor.The kinetic model for bisphenol A hydrogenation reaction is established based on the Langmuir-Hinshelwood reaction mechanism,and the first hydrogenation step is identified as the rate-determining step.It is verified that the activation energies required for the hydrogenation of bisphenol A and 4-(2-(4-hydroxycyclohexyl)prop-2-phenol,the intermediate,are determined to be 66.46 kJ·mol-1 and 68.07 kJ·mol-1,respectively.There is a strong correlation between the kinetic model and experimental data.
