聚乙烯气相流化床生产技术进展

ADVANCES IN GAS PHASE FLUID-BED PE PROCESS

介绍了近几年聚乙烯气相工艺四个主要进展，即ＵｎｉｐｏｌⅡ工艺、冷凝态操作技术、Ｓｐｈｅｒｉｌｅｎｅ工艺和茂金属催化剂的应用及它们的特点，并提出了在我国聚乙烯发展过程中，优先采用气相流化床工艺的建议。

The article gives emphasis to the introduction to four main advances in the gas phase PE process-Unipol ⅡProcess.condensing mode technology.Spherilene proces and application of metallocene catalysts in gas phase PE process, and their features.It is suggested that priority be givento gas phase fluid-bed process during the expansion of PE capacity in our country.
