ABSTRACT:
The present invention relates to a fluidized bed reactor in which olefins are polymerized or copolymerized in a bed formed by particles being polymerized and fluidized with the aid of a circulating gas. In the reactor, a circulating gas is fed from a gas space above the fluidized bed into the lower part of the reactor. The lower part of the reactor includes an annular space having an defined by an upwards tapering rotating conical surface and an outer wall defined by a downwards tapering rotating conical surface.
