世界PP工业现状及生产技术新进展

Production status and recent progress in PP commercial technologies worldwide

综述了世界聚丙烯(PP)工业的生产现状、生产工艺和催化剂的研究开发新进展。多区循环反应器技术和双峰PP技术将成为PP的主要生产工艺,Ziegler-Natta催化剂将不断向系列化、高性能化方向发展,茂金属催化剂的应用将进一步得到发展,非茂单活性中心催化剂将成为研究开发的热点。

This paper reviewed the recent progress in research and development of commercial technologies and catalysts of polypropylene （PP） as well as the production status of PP worldwide. The technologies of multizone circulating reactor and bimodal PP were predicted to take the dominant position in the production of PP. Ziegler-Natta catalysts would continue to develop in the direction of forming a series product and possessing high performance. The application of metallocene catalyst would be further expanded. Non-metallocene catalyst with a signal active site would become a hotspot of the research and development in the PP field.
