【Abstract】 The intrinsic kinetics of FBD shift reaction catalyst is studied in this paper. An isothermal integral tubular reactor is employed to get experimental data. The concentration of reactant gas at the reactor exit is analyzed by gas chromatography under the reaction conditions of temperature 300～460 °C , pressure 0.8～2.8 MPa, and space velocity 7 000～9 000 h -1 . The intrinsic kinetics model taking the form of power law type is built, and the activation energy and pre exponential factor are obtained from the experimental data. The results show that the experimental data agree well with calculated data from the kinetics model.更多还原
