The plastic waste accumulation has been increasing and a solution other than landfilling is required. Due to the high cost of recycling, thermal treatment could be an option. However, the existence of polyvinyl chloride (PVC) would release hydrochloric acid which would cause emission problems as well as damage to the reactor systems. The thermal degradation of PVC has been studied over the years. However, the mechanism of the PVC thermal degradation is not fully developed. Specifically, the mechanism of the PVC thermal degradation at medium temperatures, which is more practical for industries, is still lacking. A degradation temperature of 300 °C was used to study the dehydrochlorination behavior of PVC. A rather comprehensive mechanism with four consecutive reactions has been developed based on the micro-pyrolysis experiments and has been validated and proved by predicting the mass loss, chlorine content, heat content and elemental composition with high precision experimental data in different reactors with/without heat transfer coupling.

塑料废物的积累一直在增加，并且需要除填埋之外的解决方案。由于回收成本高，可以选择热处理。但是，聚氯乙烯（PVC）的存在会释放出盐酸，这将导致排放问题以及对反应器系统的损害。多年来已经研究了PVC的热降解。然而，PVC热降解的机理还没有得到充分发展。具体而言，仍缺乏在工业上更实用的中温下PVC热降解的机理。降解温度为300°C，用于研究PVC的脱氯化氢行为。
