摘要
综述了国内外茂金属聚乙烯(mPE)市场供需状况,重点分析了mPE生产工艺、催化剂研究进展,以及我国mPE工业化生产现状。指出:2019年,我国mPE产品自给率不足22%,迫切需要不断优化均相茂金属催化剂性能,并且开发新型茂金属均相催化剂体系和负载化体系,以提高催化剂综合使用效率,减少其用量和成本;紧盯与国外公司的差距,结合茂金属催化剂的研发,加强mPE新产品的开发和工业化优化,并稳定提升其产品质量,切实提高我国mPE产品的自给率,助力我国石化产品结构向高端化转型。
The supply and demand status of the metallocene polyethylene(mPE)market at home and abroad had been reviewed with 22 references.Especially,the analyzations of mPE production process,catalyst research progress and industrialization production of mPE in China had been focused on.It was pointed out that the self-sufficiency rate of mPE products in China in 2019 was less than 22%.It was urgent to continuously optimize the performance of homogeneous metallocene catalysts and develop new relevant homogeneous catalysts&supporting systems,so as to improve the comprehensive utilization efficiency and reduce the costs and usage quantity of metallocene catalysts.The development of the new mPE products&their industrialization optimization would be strengthened by focusing on the gaps with foreign companies and combining with the ongoing research&development of metallocene catalysts,and to stabilize and improve the quality of related mPE products at the same time to effectively enhance the self-sufficiency rate of mPE products within China,and to help the petrochemical product structures of China transform to the high-end.
