It shows that the two methods can be used to obtain kinetic parameters of polypropylene pyrolysis. Under the condition of coal fly ash of 2% weight,kinetic enthalpy is 196 kJ/mol by constant temperature method and 233 kJ/mol(n=1) by TG.

• 结果表明,这两种方法都适用于聚丙烯的催化降解,且粉煤灰含量为2%25时,恒温模型计算得到的反应活化能为196kJ/mol,TG模型计算的结果是233kJ/mol(反应级数为1)。
