The present study explores thermo-chemical potential of two biomasses namely; Phoenix dactylifera seed (PDS) and Aegle marmelos L core (AMP). These biomasses contain high amount of cellulose and exhibit heating value of 3-18 MJ/kg. The thermal kinetic of both the biomasses have been extensively studied using thermogravimetric analysis (TGA) at four different heating rates 5, 10, 15, and 20 °C/min. Kinetic analysis was carried out using three model-free techniques including Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and Starink. The average activation energy has been found to be 173.75, 172.94 and 170.71 kJ/mol, for PDS whereas 170.26, 167.24 and 164.80 kJ/mol, for AMP analyzed through KAS, FWO and Starink methods, respectively. Further, among all these models, the Starink model exhibits better result for the biofuels potential point of view.
本研究探索了两种生物质的热化学势,分别为:海枣种子(PDS)和酸橙核(AMP)。这些生物质含有大量的纤维素,其热值为 3-18 MJ/kg。使用热重分析(TGA)在四个不同的加热速率(5、10、15 和 20°C/min)下,对这两种生物质的热动力学进行了广泛的研究。使用三种无模型技术(包括 Flynn-Wall-Ozawa(FWO)、Kissinger-Akahira-Sunose(KAS)和 Starink)进行了动力学分析。通过 KAS、FWO 和 Starink 方法分析,PDS 的平均活化能分别为 173.75、172.94 和 170.71 kJ/mol,AMP 为 170.26、167.24 和 164.80 kJ/mol。此外,在所有这些模型中,Starink 模型从生物燃料潜力的角度来看,表现出更好的结果。
