James Wei 及其同事对于单分子反应系统的动力学研究给出了较详尽的结构分析和理论分析。本文根据他们的理论分析,应用反应物组成向量α(0)、反应时间t 和t 时刻的产物组成向量α(t)之间的关系:α(t)=x(expλt)x~(-1)α(0)设计实验,仅需要少量的张成整个组成空间的实验数据,通过适当的矩阵运算,就可以方便地求得复杂反应系统中的各速度常数。该法同Wei 等人建议的实验方法相比具有方法简便,对实验精度要求较低等优点。本文通过作者对己烷在Pd/HM 型催化剂上异构化反应的动力学研究结果,说明了该法的可行性,可望在石油炼制和石油化工催化过程的动力学模型开发中得到更广泛的应用。
James Wei and colleagues gave more detailed structural and theoretical analyzes of the kinetics of single molecule reaction systems. According to their theoretical analysis, the relationship between the product composition vector α (t) and the product compositional vector α (t) at the reaction time t and t is obtained according to their theoretical analysis: α (t) = x ) α (0) The design experiment requires only a small amount of experimental data to form the entire composition space. Through appropriate matrix operations, each velocity constant in a complex reaction system can be easily obtained. Compared with the experimental method proposed by Wei et al., The method has the advantages of simple method and lower requirement on experimental precision. In this paper, the kinetics of the isomerization of hexane on Pd / HM catalyst is demonstrated by the author. The feasibility of this method is demonstrated. It is expected to be more useful in the kinetic model development of petroleum refining and petrochemical catalysis Wide range of applications.
