摘要: 用CS-2-G/ZN1l8混合催化剂替代ZN118催化剂,在300 kt/a的Spherizone工艺气相聚丙烯装置上进行工业试生产,生产拉丝料聚丙烯LHP456J,考察了CS-2-G型催化剂在该装置上掺混使用的可行性。结果表明:CS-2-G/ZN1l8混合催化剂在Spherizone工艺气相聚丙烯装置上具有较强的适应性,整个试用过程装置安全平稳运行,产品质量合格。LHP456J was produced in 300 kt/a Spherizone gas-phase polypropylene plant using CS-2-G/ ZN1l8 as a substitute catalyst for ZN118. The feasibility of mixing CS-2-G catalyst in the Spherizone gas-phase polypropylene plant was investigated. The results show that the mixed catalyst CS-2-G/ZN1l8 has strong adaptability to the Spherizone process in the gaseous polypropylene plant. The whole trial process of the plant runs safely and stably, and the product quality is qualified.
