Research on low-temperature ozidation and pyrolysis of coal by thermal analysis ezperiment

摘要：

In order to understand the law of low-temperature oxidation and pyrogenation well, thermal analyzer is used to study the oxidation and pyrogenation of coal in Yangquan below 150℃. Through the TG-DSC curves, the heat release of two kinds of experiments is compared. Combining with the curve, the polynomial form of the mechanism is set up to analyze the function of its dynamic characteristics. It shows that the process of low-temperature oxidation is a clear exothermic oxidation process contrasted with the pyrogenation process and the oxidation of coal needs smaller activation energy than pyrogenation in nitrogen atmosphere. The mechanism is different from the oxidation at ordinary low-temperatures and the process of pyrogenation is the function of polynomial. The mechanism function is applied to the TG and DSC curves.
