【摘要】 利用TA Q600同步热分析仪，在空气氛围下，2～3mg粒径为250～420μm的樟子松松果颗粒以10、15、20、25 K/min的升温速率线性升温至1 073 K左右，采用模型拟合法（Coats-Redfern法、Zsako法、Satava-Sestak法）和无模型拟合法（KAS法、Doyle法、FWO法）对松果热解动力学参数进行求解和比较，计算反应活化能E值、指前因子A。结果表明：松果热解主要包括4个阶段，主要质量损失阶段失重率占85%以上。无模型拟合法得到平均活化能分别为74.3 kJ/mol(Doyle法）、71.8 kJ/mol(FWO法）、68.3 kJ/mol(KAS法），且KAS法的活化能与指前因子曲线拟合R ~2>0.95；模型拟合法得到平均活化能为65.4 kJ/mol(Zsako法）、62.4 kJ/mol(Satava-Sestak法）、56.4kJ/mol(Coats-Redfern），且Zsako法、Satava-Sestak法的平均活化能更接近无模型较准确的活化能，其中Satava-Sestak法的指前因子可反映热解反应机理的复杂性。建议将KAS法与Satava-Sestak法结合，更好地评价樟子松松果的燃烧性。更多还原

【Abstract】 Using the TA Q600 synchronous thermal analyzer,the2～3 mg pinecone particles with a particle size of 250～420μm were linearly heated to about 1 073 K at the heating rate of 10 K/min,15 K/min,20 K/min and 25 K/min in an air atmosphere.Model fitting method (Coats-Redfern method,Zsako method,Satava-Sestak method) and no model fitting method (KAS method,Doyle method,FWO method) were used to solve and compare the kinetic parameters of pine pyrolysis,and the value of activation energy E and pre-index factor A were calculated.The results show that the pyrolysis of Pinus sylvestris pine cones includes four stages,and the mass loss ratio of the main mass loss stage is more than 85%.The average activation energies obtained by the modelless fitting method were 74.3 kJ/mol (Doyle method),71.8 kJ/mol (FWO method) and 68.3 kJ/mol (KAS method),respectively,and the fitting curves of the activation energies of KAS method and the predigital factor were>0.95.The average activation energies obtained by model fitting were 65.4kJ/mol (Zsako method),62.4 kJ/mol (Satava-Sestak method),56.4 kJ/mol (Coats-Redfern).The average activation energy of Zsako method,and Satava-Sestak method is closer to the activation energy without model,and the pre-exponential factor of Satava-Sestak method can reflect the complexity of the pyrolysis reaction mechanism.This paper suggests that KAS method and Satava-Sestak method should be combined to better evaluate the burning property of Pinus sylvestris pine cones.更多还原
