Intrinsic kinetics of dehydrogenetion of cyclopentanol was investigated in the presence of Raney-Ni catalyst.Analysis on reaction thermodynamics denied occurrence of the hydrogenation of cyclopentanone,the reverse reaction.Based on reaction mechanism discussion it was reasonable to express the dehydrogenation rate equation of cyclopentanol in an exponential form.Parameters of the intrinsic kinetics model were solved by the Gauss-Newton method based on the experimental data.Through statistic test and residual error distribution the intrinsic kinetics model was proved to be adequate.Rate equation for the catalytic reaction was-dc/dt=kc~2_A,where E_a=63.05 kJ/mol;and k=3.1×10~4×exp(-63 050/RT).Micromechanism of dehydrogenation was also discussed.
