Abstract This work aims to explore the scaling up process of lab developed heterogeneous metallocene catalyst in a pilot-plant scale fluidized bed reactor in comparison of benchmark catalyst producing polyethylene. The catalyst performance has been evaluated through copolymerization behaviors and polymerization kinetics. The produced polymers are analyzed in revealing the scale up effect of the catalyst. It was found that the catalyst particle size distribution shows very similar size distribution compared to the industrial catalyst and good particle morphology, which will benefit the gas phase fluidized bed operation. Compared to the benchmark HP-100, PME-18 shows better catalytic parameters in the ethylene/1-hexene polymerization behavior and reaction kinetics. The final product demonstrates very similar particle size distribution and polymer properties, which will obviously influence the product quality and production state.

中试流化床反应器中高性能气相乙烯聚合茂金属催化剂研究(一)实验分析

摘要 本工作旨在探索实验室开发的非均相茂金属催化剂在中试规模流化床反应器中的放大工艺,并与生产聚乙烯的基准催化剂进行比较。催化剂性能已通过共聚行为和聚合动力学进行评估。分析产生的聚合物以揭示催化剂的放大效应。发现与工业催化剂相比,催化剂粒度分布显示出非常相似的粒度分布和良好的颗粒形态,这将有利于气相流化床操作。与基准 HP-100 相比,PME-18 在乙烯/1-己烯聚合行为和反应动力学方面显示出更好的催化参数。
