通过对抚顺油页岩中有机质与矿物质热分解过程的考察,初步阐明了两者单独热解时各自的热分解行为;同时确定了有机质与矿物质热分解反应的级数、反应速率常数及相应的速率方程。与抚顺油页岩热分解过程的对比表明:矿物质对有机质热分解的影响,突出地表现在热分解初期,它使有机质的热稳定性得到提高。进入主要的热分解阶段后,油页岩与有机质的热分解特征及动力学参数无明显差异,故可认为油页岩的热分解过程基本上是有机质热分解的反映。
Through the investigation of the thermal decomposition of organic matter and minerals in the oil shale, the thermal decomposition behavior of the two in the separate pyrolysis was clarified. At the same time, the series of thermal decomposition reaction of organic matter and minerals, the reaction rate constant and The corresponding rate equation. Compared with the thermal decomposition process of Fushun oil shale, the results show that the influence of minerals on the thermal decomposition of organic matter is prominent in the initial stage of thermal decomposition, which enhances the thermal stability of organic matter. After entering the main thermal decomposition stage, the thermal decomposition characteristics and kinetic parameters of oil shale and organic matter are not significantly different. Therefore, the thermal decomposition process of oil shale is basically the reflection of thermal decomposition of organic matter.
