In this work, the low-temperature pyrolysis of a real plastic mixture sample collected at a WEEE-authorised recycling facility has been investigated. The sample was pyrolysed in a batch reactor in different temperature and residence time conditions and auto-generated pressure by following a factorial design, with the objective of maximising the liquid (oil) fraction. Furthermore, the main polymers constituting the real sample were also pyrolysed in order to understand their role in the generation of oil. The pyrolysis oils were characterised and compared with commercial fuel oil number 6. The results showed that in comparison to commercial fuel oil, pyrolysis oils coming from WEEE plastic waste had similar heating values, were lighter and less viscous and presented similar toxicity profiles in fumes of combustion.
在这项工作中，对在一家电子电气设备授权回收设施收集的真实塑料混合物样品进行了低温热解研究。该样品在间歇式反应器中于不同温度和停留时间条件下进行热解，并通过析因设计自动生成压力，目的是使液体（油）馏分最大化。此外，还对构成真实样品的主要聚合物进行了热解，以了解它们在油生成过程中的作用。对热解油进行了表征，并与6号商业燃料油进行了比较。结果表明，与商业燃料油相比，来自电子电气设备塑料废料的热解油具有相似的热值，更轻、粘度更小，并且在燃烧烟雾中呈现出相似的毒性特征。
