DQC401催化剂在环管工艺PP装置上的工业应用

介绍了DQC401催化剂在环管工艺聚丙烯(PP)装置的应用情况。DQC401是中国石化催化剂有限公司北京奥达分公司开发的第四代高效球形PP催化剂,为DQ-Ⅲ催化剂的改进型,适用于Spheripol工艺。工业应用表明:DQC401催化剂具有活性高、氢调敏感性好、粒径分布窄、聚合物等规指数大等特点,满足均聚物、抗冲共聚物、无规共聚物生产的需要。

Industrial Application of DQC401 Catalyst in Polypropylene Plant with Loop Polymerization Process

It was introduced that the application of DQC401 catalyst in polypropylene（PP） plant with loop polymerization process. The DQC401 catalyst, which was fourth-generation ball-type catalyst for Spheripol process in polymerization of PP and DQ-m catalyst improved product, was developed by organization of the authors. The results of application in plant of the PP show that the DQC401 catalyst has high activity,excell- ent hydrogen response behavior, narrow particle size distribution and high isotactic index of the product. Those advantages make it applicable for prodouction of homopolymer, impact copolymers and random copolymer.
