During the underground coal gasification process, a large amount of heat will be released, causing the surrounding rock in the goaf to undergo a high-temperature baking process. Therefore, it is essential to study the pyrolysis characteristics and mechanism of rocks. In this paper, the red sandstone in Linyi city of China is taken as an example. According to the results of thermogravimetric analysis in argon and air, the thermokinetic parameters are calculated by non isothermal pyrolysis kinetic...
