ABSTRACT:
An improved angled annular deflector for a gas-phase polymerization reactor and improved method for delivery of a stream of polymerizable fluid to a gas-phase polymerization reator. The angled annular deflector has an outer surface with a conical shape, an inner surface, and an inner cavity along a central axis, said cavity open at both ends, the inner surface having a first end and a second end, and the first end of the inner surface mated to the apex end of the outer surface: and an upper surface mated to the base end of the outer surface and to the second end of the inner surface; wherein the outer surface, the inner surface, and the upper surface form a substantially closed chamber. The angled annular deflector being adapted to associate with a cone-shaped bottom portion of a fluidized bed polymerization reactor vessel.
