聚苯乙烯塑料废物在静态间歇式反应器中热解，挥发性产物在500、600和700°C下二次裂解。分析了冷凝热解油中多环芳烃（PAH）的含量。油中苯乙烯、苯乙烯低聚物和烷基化衍生物含量高。此外，油中含有高浓度的多环芳烃，其中一些具有已知的生物活性。PAH被发现增加与热解温度。使用ZSM-5沸石的油的催化改质降低了苯乙烯低聚物的浓度并增加了PAH的浓度。
Polystyrene plastic waste was pyrolysed in a static batch reactor with secondary cracking of the volatile products at 500, 600 and 700°C. The condensed pyrolysis oil was analysed for its content of polycyclic aromatic hydrocarbons (PAH). The oils were high in styrene, styrene oligomers and alkylated derivatives. In addition, the oil contained PAH in high concentration, some of which were of known biological activity. The PAH were found to increase with increasing pyrolysis temperature. Catalytic upgrading of the oils using zeolite ZSM-5 reduced the concentration of styrene oligomers and increased the concentration of PAH.
