Abstract	The kinetics for the pinene hydrogenation to pinane, the transformation of renewable biomass to useful chemicals, using spent fluid catalytic cracking catalyst (SFCC) supported nickel (Ni/SFCC), has been extensively investigated without any organic solvent, in the temperature range 373–393 K and the hydrogen pressure of 2–6 MPa in the absence of diffusional limitation. The non-noble metal catalyst was synthesized by incipient wet impregnation method and characterized by SEM, XPS and ICP. The catalytic effects of various parameters (catalyst weight, temperature and hydrogen pressure) on the reaction were reported, and the novel catalyst exhibited good activity. 17 kinds of Langmuir–Hinshelwood surface reaction mechanisms for the hydrogenation of pinene were proposed and derived. The best model described the experimental data with physically meaningful parameters was obtained by parameter diagnostics and a non-linear regression analysis, in which the surface reaction of adsorbed hydrogen atoms and pinene molecules over nickel catalyst was the rate-controlling step during the entire hydrogenation process. The activation energy of pinene surface hydrogenation to pinane was 118 ± 2.61 kJ mol$^{−1}$ calculated from the Arrhenius plot.
