Four heating rate profiles (2.5, 5, 10 and 20 K min(-1)) were applied, with a final temperature 1123 K. Two-stage decomposition was observed in the experiments. During the stage 1, when the temperature is lower, only weaker chemical bonds are destroyed and some small gaseous molecules are produced. During the stage 2, when temperature is higher, the cracking is faster and stronger chemical bonds are broken, so that larger molecules decompose into small molecules in the gaseous phase. Kissinger (differential) and Coats-Redfern (integral) methods were applied to thermogravimetric data to obtain kinetic parameters (activation energy and Arrhenius constant).eninfo:eu-repo/semantics/closedAccess[No Keyword]Article244547560WOS:0002518620000062-s2.0-38349121368Q2Q2
