摘要: 针对表面中毒并伴有平衡死区二维圆柱状催化剂的反应-扩散偏微分方程组的特殊性,引入有限元方法求解该类问题,建立了求解步骤。实际计算所得效率因子与实验值对照表明,本法结果准确,过程简单,容易推广应用于各种相类似的体系。

Abstract: On the basis of the distinguishing features of two-dimensional reaction -diffusion equations describing the surface poisoned cylindrical catalyst with equilibrium dead zone, Finite Element Method (FEM) is used to solve this kind of problem, which is often difficult to solve for other methods. A comparison of calculated effectiveness factors with experimental data shows that FEM has the advantages of simplicity and accuracy and it is easy to be used to analogous systems.
