Abstract: In this paper, the kinetic model of butynediol hydro-genation to 1, 4-buta-nediol by using Pd/γ-Al2O3 catalyst was studied. The kinetic experiments were performed, and the evaluation of various rate equations based on different mechanism were made. The multiple series-parallel reactions thus chosen were solved by Runge-Kutta method. Finally, the activation energies of various reactions were calculated.
