The aim of this work was to study the thermal degradation of grass (Cymbopogon schoenanthus) under an inert environment at three heating rates, including 10, 30, and 50°Cmin in order to evaluate its bioenergy potential. Pyrolysis experiments were performed in a simultaneous Thermogravimetry-Differential Scanning Calorimetry analyzer. Thermal data were used to analyze kinetic parameters through isoconversional models of Flynn-Wall-Ozawa (FWO) and Kissenger-Akahira-Sunose (KSA) methods. The pre-exponential factors values have shown the reaction to follow first order kinetics. Activation energy values were shown to be 84-193 and 96-192kJmol as calculated by KSA and FWO methods, respectively. Differences between activation energy and enthalpy of reaction values (∼5 to 6kJmol) showed product formation is favorable. The Gibb's free energy (173-177kJmol) and High Heating Value (15.00MJkg) have shown the considerable bioenergy potential of this low-cost biomass.
本工作旨在研究三种加热速率（10、30 和 50°Cmin）下惰性环境中草（Cymbopogon schoenanthus）的热降解，以评估其生物能源潜力。在同步热重-差示扫描量热仪中进行热解实验。通过 Flynn-Wall-Ozawa（FWO）和 Kissenger-Akahira-Sunose（KSA）方法的等转化率模型，利用热数据分析动力学参数。前指数因子值表明反应遵循一级动力学。由 KSA 和 FWO 方法计算的活化能值分别为 84-193 和 96-192kJmol。反应焓和活化能值之间的差异（约 5 至 6kJmol）表明产物形成是有利的。吉布斯自由能（173-177kJmol）和高热值（15.00MJkg）表明这种低成本生物质具有可观的生物能源潜力。
