Method for olefin polymerization in a gas phase reactor comprising an uprising pipe unit and a downcomer |
| abstract |
It is possible to either homopolymerize ethylene or polymerize ethylene in a gas phase polymerization reactor comprising an up tube unit in which the growing polymer particles flow upward under fluidization, fast fluidization or transport conditions, and a downcomer pipe in which the growing polymer particles flow downward in a densified form Wherein the holding up amount of the polymer particles in the downcomer is 55% to 80% by weight of the total hold up amount of the polymer particles in the gas phase polymerization reactor. |
