Synergistic Effect and Chlorine-Release Behaviors During Co-pyrolysis of LLDPE, PP, and PVC.

摘要: Plastic wastes are environmentally problematic and costly to treat, but they also represent a vast untapped resource for the renewable chemical fuel production. Pyrolysis has received extensive attention in treatment of plastic because its technical maturity. A sole polymer waste is easy recycle by any means physical or techniques. However, majority life mixtures hard separate, which make pyrolysis complicated compared with pure difference physical/chemical properties. This work focuses on synergistic effect impact chlorine removal from chlorinated mixtures. The behavior was investigated terms thermogravimetric analysis, corresponding kinetics were analyzed according distributed activation energy model (DAEM). results show that existed mixture LLDPE, PP, PVC, DAEM could well predict behavior. decomposition LLDPE/PP occurred earlier than calculated ones. weakened increase LLDPE As removal, PP hindered PVC during pyrolysis. noticeable negative dechlorination observed after introduction PP. Besides, chlorine-releasing temperature became higher ([LLDPE/PVC (1:1), PP/PVC LLDPE/PP/PVC (1:1:1)]. These imply more difficult thermal conversion. In other words, should be paid both high-temperature corrosion high-efficient practical. data helpful utilization yearly increased wastes.
