摘　　要：The intrinsic kinetics of water gas shift reaction over Pt/CeO 2-ZrO 2 was investigated.Experiments were carried out by means of orthogonal design.Parameters of power-type rate model of water gas shift reaction were determined by the non-linear least-square parameter estimation method.The kinetics of water gas shift reaction over Pt/CeO 2-ZrO 2 was different from that of common commercial catalysts.The accuracy of experimental data and kinetics model was proved by F-examination.The intrinsic kinetics of water gas shift reaction over Pt/CeO2-ZrO2 was investigated.
