| 摘 要： | 借助于奇异理论和突变理论,本文对单颗粒催化剂的多定态特性进行了分析。得到了反应为一级不可逆放热反应时系统定态模型方程解的结构以及可能具有的歧化图型式;对非一级反应系统,利用区域搜索算法得到了其系统定态模型方程突变集合在操作参数平面上的投影图,分析了反应动力学表达式及动力学参数的变化对体系多定态特性的影响。

| Abstract: | By means of the sigularity theory and catastrophe theory, the theoretical analysis for the multiple steady state features of a single catalyst pellet was presented in this paper. When a first order irreversible exothermic reaction occurs on the single catalyst pellet surface, the solution structure of the steady state equation and the possible type of the bifurcation diagrams of the system were determined. With the help of the regional search algorithm, the projections of catastrophe set of some other model equations onto operation parameter plane were obtained. The effects of the kinetic expressions and kinetic parameters on the multiple steady state features of the system were predicted. |
