报告的动力学参数之间的差距，以及挥发性物种的演变，整体煤的分解已被归因于不同的煤的类型进行研究，以及在所采用的实验技术。在这项研究中，被认为是流化床中的甲烷演化的数据报告，并发现在很大程度上是不敏感的煤的类型。此外，分布式动力学参数获得使用加热网格，夹带流和缓慢加热技术被发现代表流化床数据的煤粉和大颗粒煤，提供的运输机制也被考虑在内。
The disparity between reported kinetic parameters for overall coal decomposition as well as volatile species evolution has been attributed to differences in the type of coal being studied as well as in the experimental technique employed. In this study, data reported for methane evolution in fluidized beds are considered and are found to be largely insensitive to coal type. Additionally, distributed kinetic parameters obtained using the heated grid, entrained flow and slow heating techniques are found to represent the fluidized bed data for both pulverized and large coal particles, provided that the transport mechanisms are also taken into account.
