摘　　要：采用内循环无梯度反应器 ,对 FBD变换催化剂进行了宏观动力学研究。实验采用 9.1 mm× 7.7mm圆柱状工业粒度催化剂 ,反应温度 3 0 0～ 460°C,压力 0 .8～ 2 .9MPa。建立了幂函数型宏观动力学模型 ,采用改进的高斯 -牛顿法 ,由实验数据获得了模型中的参数。Using internal circulation gradientless reactor, the macroscopic reaction kinetics of FBD CO shift reaction catalyst of original particle size is studied. The concentration of reactant gas at the reactor exit is analyzed under the conditions of temperature from 300 °C to 460 °C and pressure from 0.8 MPa to 2.9 MPa . The power law type macrokinetic model is obtained to depict the macroscopic reaction rates. The results calculated from the macrokinetic model are in good agreement with the experimental data. The results of significance test shows that the model is reliable.
