Process for polymerization of Olefins in a gas phase reactor, which comprises a vertical Tube Upward and downward vertical Tube

摘要

A process for preparing a polymer of ethylene comprising homopolimerizar copolimerizar Ethylene or Ethylene with one or more comonómeros in a gas phase polymerization reactor which comprises aUpward vertical Tube, in which the growing Polymer particles Flow upwards in terms of Fluidization or Rapid Transport Tube, and a vertical downwardThe Growing Polymer particles Flow down in Densified,Where retention of Polymer particles in the vertical Pipe downward Is 55% by weight to 80% by weight of the total content of Polymer particles in the Reactor in Gase Phase polymerizationOsa.
