摘要

本研究的重点是通过在 50-50 平衡混合物中加入枣核来改善聚对苯二甲酸乙二酯（PET）热解结果。通过使用 Coats-Redfern 方法进行热分析，确定了加入枣核对共热解过程的影响，从而估算出 PET-Date 混合物的活化能和预指数。结果表明，改性混合物的大多数反应机理都表现出更高的性能，所需的反应能量平均降低了 70%。因此，对 PET 高温分解产生了积极的影响，从而凸显了其在生物质掺入方面的潜力。这项研究为优化可持续废物管理和资源利用的共热解过程提供了宝贵的见解。

Kinetic and thermodynamic analysis of the PET-date seed mixture co-pyrolysis using Coats-Redfern method

This study focuses on improving the polyethylene terephthalate (PET) pyrolysis outcome by incorporating date pits in a balanced 50–50 mixture. The effect of date pit addition on the co-pyrolytic process is determined via thermal analysis using the Coats-Redfern method, which provides an estimation of the activation energy and the pre-exponential factor of the PET-Date mixture. The results demonstrate that the majority of the reaction mechanisms exhibit enhanced performance for the modified mixture, requiring 70 % less reaction energy on average. Hence, a positive effect is observed on the PET pyrolysis, thus highlighting its potential for biomass incorporation. This study provides valuable insights into optimising the co-pyrolytic processes for sustainable waste management and resource utilization practices.
