Application of Slurry Catalyst in Unipol Gas-phase Fluidized Bed Polyethylene Process
The polymerization catalyst is the key and core of the ethylene polymerization process,and its quality directly affects the stability of the polymerization reaction.This article mainly studies the application of S-type slurry catalyst in Unipol gas-phase fluidized bed polyethylene process,analyzes and summarizes the advantages and disadvantages of S-type slurry catalyst.The results show that compared with the early A-type slurry catalyst,the S-type slurry catalyst is more stable and controllable in the polymerization reaction,produces higher packing density of resin powder,better flow-ability of powder,and has less fine powder in the powder product.It is more suitable for the high load,long-term stable operation of Unipol gas-phase fluidized bed reactor.
