| titleOfInvention | Gas-phase polymerization process with wet zone |
| abstract | FIELD: technological processes. n SUBSTANCE: invention relates to producing olefin-based polymer in a gas phase polymerization reactor. Process includes forming a wet zone in the gas phase polymerization reactor. Wet zone is formed by maintaining a temperature less than or equal to the fluidizing medium dew point temperature +2 °C in a region of the reactor. This region is defined as the region extending from the distributor plate to 2.5 meters above the distributor plate. Catalyst with an activity of more than 50 t/kg is introduced into the wet zone. Catalyst is contacted with one or more monomers of the fluidizing medium in the wet zone under gas phase polymerization conditions. Method comprises forming olefin-based polymer particles having a bulk density in a deposited state of from 376.4 kg/m 3 (23.5 lbs/ft 3 ) and more. n EFFECT: improving the production of polymers by increasing the bulk density of the fluidized bed in the deposited state. n 8 cl, 5 dwg, 2 tbl, 4 ex |
