| 中文摘要: |
| 目的 以聚烯烃和聚对苯二甲酸乙二醇酯(PET)为研究对象综述近5年来塑料包装废弃物的化学回收技术，以期为塑料包装废弃物的资源化技术发展趋势提供参考。方法 通过收集与整理相关文献，阐述聚烯烃类以及PET包装废弃物的化学回收方法、常用催化剂、反应装置等，分析催化剂、反应装置、反应温度等条件对产物收率、成分的影响。结论 未来短期内柔性包装材料仍然会以聚烯烃、聚酯等传统石油基材料为主。化学回收是废塑料资源化的一种重要手段，传统催化剂的改良、新型催化剂的开发以及反应装置的优化将是该领域未来的研究重点。 |
| 英文摘要: |
| The work aims to review the chemical recycle technology of plastic packaging waste in recent 5 years with polyolefin and polyethylene terephthalate (PET) as the research object, so as to provide reference for the development trend of plastic packaging waste recycle technology. The chemical recycle methods, common catalysts and reaction devices of polyolefin and PET packaging wastes were clarified by collecting and sorting relevant literature. The effects of catalyst, reaction device and reaction temperature on product yield and composition were analyzed. In the short term, the flexible packaging materials will still be dominated by traditional petroleum-based materials such as polyolefin and polyester. Chemical recycle is an important means for recycling waste plastics. The improvement of traditional catalysts, the development of new catalysts and the optimization of reaction devices will be the focus of future research in this field. |
