The thermo-chemical characterization (proximate and ultimate analyses and higher heating value) of banana trunk biomass waste has been carried out. The thermo-gravimetric and differential scanning calorimetric (DSC) investigations have been made at heating rates of 10, 15, 20 and 25 °C/min. The TGA data have been used to carry out kinetic analysis and evaluate the kinetic and thermodynamic parameters using iso-conversional models. The values of activation energy increase with conversion (α) irrespective of the iso-conversional model used. The average values of activation energies (E) are found to be 386.21, 355.43, 385.77, 355.01, 379.67, and 292.78 kJ/mol for Flynn-Wall-Ozawa (FWO), Starink, Kissinger-Akahira-Sunose (KAS), Tang, Vyzovkin and Vyzovkin AIC model, respectively. The average values of change in enthalpy, Gibbs free energy, and entropy have been calculated. The reaction mechanisms of pyrolysis have been predicted using Criado's method.
已对香蕉树干生物质废料进行了热化学特性（近似分析和最终分析以及高热值）分析。在 10、15、20 和 25°C/min 的加热速率下进行了热重分析和差示扫描量热法（DSC）研究。TGA 数据用于进行动力学分析，并使用等转化率模型评估动力学和热力学参数。无论使用哪种等转化率模型，活化能的值都随转化率（α）的增加而增加。平均活化能（E）值分别为 386.21、355.43、385.77、355.01、379.67 和 292.78 kJ/mol，适用于 Flynn-Wall-Ozawa（FWO）、Starink、Kissinger-Akahira-Sunose（KAS）、Tang、Vyzovkin 和 Vyzovkin AIC 模型。计算了焓、吉布斯自由能和熵的变化平均值。使用 Criado 的方法预测了热解反应的机理。
