摘要
聚合过程强化技术是实现聚合过程效能最大化、聚合物产品结构可控化以及聚合过程和产品绿色化的有效技术手段。本文综述了聚合过程强化技术的国内外进展,从流动与混合强化、传热与传质强化、反应耦合过程强化、超临界流体强化、外场强化等方面重点分析了不同聚合过程强化技术的特点,并对聚合过程强化技术中存在的问题进行了探讨。指出聚合过程强化应注重聚合动力学特性和设备特性的有效耦合,基于聚合反应特性的过程强化方法是今后的发展方向。
Process intensification technology for polymerization is an effective technical means to maximization of the efficiency of polymerization process,controllability of polymer product structures,and green polymerization process and polymer product.Development of process intensification technology for polymerization was reviewed.The features of different process intensification methods were analyzed with emphasis in terms of flow and mixing,heat and mass transfer,reactive coupling,supercritical fluid,external field,etc.Also,the existent problems were discussed.It is revealed that process intensification technologies for polymerization should focus on the effective coupling between polymerization kinetics and polymerization equipment.Process intensification methods based on polymerization characteristics are the future directions of development.
