| Abstract: | This paper analyzed the influence of height of fluidized catalyst bed on the size of polymer powders, polymerization yield and operation period of the gas phase polyethylene (PE) plant. The results prove that increasing bed height is beneficial to scrubbing the extended section of the reactor with the polymer powders, effectively reducing the block in recycle gas loop and the agglomeration in the polymerization reactor and prolonging operation period of the PE plant. |

| Keywords: | gas phase polyethylene fluidized bed bed height control operation period |
