Abstract: The recent research developments of the recovery and reuse of PVC and its mixtures by pyrolysis are reviewed. The process, conditions, kinetic parameters, existing problems, and suggestions for improvement of PVC pyrolysis are discussed. Two of the important problems to be solved for PVC pyrolysis are the separation and recovery of HCl produced, and the minimization of the chlorocarbons content of the liquid product. Lowering pyrolysis temperature and increasing pyrolysis efficiency should be emphasized.

摘要： 综述了以热裂解工艺(包括热裂解与化学处理相结合的工艺)回收利用废弃PVC及PVC混合塑料的近期进展，讨论了PVC热裂解的工艺过程、工艺条件、动力学参数、存在问题及改进方向。认为PVC的热裂解必须解决的首要问题是分离回收所产生的HCl及控制液态产品的卤代烃含量，而降低热裂解温度和提高热裂解效率则是其改进重点。
