| 摘 要： | 本文考察了三种类型干酪根以及抚顺和茂名油页岩热解反应的动力学特性,对由平行反应模型所求得的表观活化能及视频率因子进行了数学关联。关联式表明,视频率因子的对数值与表观活化能成一直线关系。由此关系可以推出,所有平行反应在某一特定温度下具有一个相同的反应速率常数。根据直线的斜率,还可以比较不同类型干酪根热降解反应的难易程度。

| Abstract: | In this paper the kinetic property of thermodegradation of three kinds of kerogen and oil shales in Fushun and Maoming are investigated. The correlation equations of apparent activation energy and frequency factor in Tissot's parallel reaction model are determined. From these equations, a plot of In Aj against Ej resulting in a straight line can be obtained, and it can be derived that the specific rate constants of all parallel first order reactions for a certain kerogen (or oil shale) are identical at a specific temperature. Based on the slopes of the straight lines, the comparison between reactivities of various kerogens can be determined. |
