A thermogravimetric analysis is used to analyze the thermal kinetics and investigate the synergistic effects between (AP) and waste tires (WTS) in a temperature range of 50-900 °C under three heating rates (15, 25, and 35 °C/min). Two model-free methods (FWO and KAS) and a model-fitting method (CR) were applied to calculate the activation energy. Results revealed that heating rates had no significant effect on the pyrolysis operation. The addition of WTS improved the thermal degradation of the samples as the samples had more than one stage during the main reaction period. A promoting synergistic effect was found in the blend 75A25WT and obtained the lowest activation energy among all the blends without a catalyst, while the blend 50A50WT exhibited an inhibiting effect. On the other hand, the addition of HZSM-5 accelerated the reaction time and obtained the lowest activation energy among all the blends without a catalyst. Furthermore, ΔW of 75A25WT+C was the lowest, indicating that the blend with a catalyst exhibited the strongest synergistic effect. This research confirmed that the addition of WTS improved the thermal parameters of the samples and clarified the capacity of HZSM-5 to reduce the activation energy.
采用热重分析方法,在 50-900°C 的温度范围内,以 3 种升温速率(15、25 和 35°C/min),分析了(AP)与废轮胎(WTS)之间的热动力学和协同效应。应用了两种无模型方法(FWO 和 KAS)和一种模型拟合方法(CR)来计算活化能。结果表明,升温速率对热解过程没有显著影响。WTS 的加入改善了样品的热降解性能,因为在主反应期内,样品有多个阶段。在没有催化剂的情况下,发现 75A25WT 混合物具有促进协同效应,并获得了所有混合物中最低的活化能,而 50A50WT 混合物则表现出抑制效应。另一方面,HZSM-5 的加入加速了反应时间,并获得了所有没有催化剂的混合物中最低的活化能。此外,75A25WT+C 的ΔW 最低,表明催化剂混合物表现出最强的协同效应。这项研究证实了 WTS 的加入提高了样品的热参数,并阐明了 HZSM-5 降低活化能的能力。
