摘要
PROBLEM TO BE SOLVED: To provide a gas phase fluidized bed apparatus which enables retention of fluidized bed-forming particles easy to cause segregation, particularly small mass particles and fluidized bed particles having a smaller diameter in the upper region of the gas phase fluidized bed apparatus, a gas phase fluidizing method and a process for producing a polymer which use this apparatus.;SOLUTION: The gas phase fluidized bed apparatus 1 has a cylindrical member 10 which forms a flow channel having a narrow part 14, a gas dispersion plate 12 which is provided below the narrow part 14 of the flow channel and supplies a first gas into the flow channel to form a fluidized bed 13, and a gas blowing part 60 which supplies a second gas to the narrow part 14 of the flow channel without the aid of the gas dispersion plate 12. The narrow part 14 of the flow channel is provided below the powder surface of the fluidized bed 13 formed on the gas dispersion plate 12.;COPYRIGHT: (C)2009,JPO&INPIT
