| 摘 要： | 采用等温管式积分反应器,在(550~750) K、(2.0~3.5) MPa和空速(15~30) L·(g·h)-1条件下，对新型钴钼系耐硫变换催化剂进行变换反应本征动力学研究。建立了包含压力项的幂函数型动力学模型，根据实验测定数据，结合具有全局寻优能力微粒群算法和求解微分方程的龙格-库塔法，通过迭代寻优对变换反应动力学模型进行参数估计，获得高度显著、可信的动力学模型。结果表明，在催化剂上进行变换反应时，反应速率对CO组分分压变化的敏感性较低，H2O组分分压对反应速率的影响较大，高汽气比下催化活性较高。

| Abstract: | The intrinsic kinetics of new cobalt molybdenum sulfur-tolerant catalyst for shift reaction was studied in an isothermal integral tubular reactor under the reaction condition of temperature (550-750) K,pressure (2.0-3.5) MPa and space velocity (15-30) L·(g·h)-1.The intrinsic kinetics model taking the form of power function which included the pressure was built.Using particle swarm optimization and Runge Kutta algorithm,the parameters in the kinetics model were fit to the experimental data.The accuracy and the correlating degree of experimental data and calculated model were verified by F test and correlation index test.The results showed that the reaction rate was not sensitive to pressure change of CO component but was sensitive to the pressure of H2O component.High catalytic activity was obtained under high steam gas ratio. |
