作为复杂反应体系动力学分析的有效方法,集总理论及其在动力学分析中的应用进行了大量报道。为此,对精确集总、近似集总及集总的选择等集总理论研究概况进行了较为全面的综述和分析,指出了集总理论研究中存在的问题,探讨了集总理论研究进一步发展的方向及主要解决的问题。作为集总理论在复杂反应体系动力学分析中应用的范例,分别介绍了两种集总处理方法———离散集总和连续集总方法在催化裂化和石脑油水蒸气转化反应体系动力学分析中的应用。
As an effective method for the kinetic analysis of complex reaction systems, lumped theory and its application in dynamic analysis have been extensively reported. To this end, a comprehensive overview and analysis of the general theories of lumped theory such as exact lumped, approximate lumped, and lumped choices is given, the problems existing in the study of lumped theory are pointed out, and the further development of lumped theory is discussed The direction and the main problems to be solved. As an example of the application of lumped theory in the kinetic analysis of complex reaction systems, two kinds of lumped methods, discrete totalizers and continuous lumped methods, are introduced respectively in the kinetic analysis of catalytic cracking and naphtha steam reforming reaction systems Applications.
