A fluidized bed reactor and operating process is disclosed, the reactor including distributor plate means to provide distribution of fluid passing upwardly into a fluidized bed; a mixing chamber positioned below the distributor plate means; fluid entry means, preferably at the base of the reactor, for the passage of fluid into the reactor; flow deflector means associated with the entry means for providing at least an upwardly fluid flow path and an outward fluid flow path along the wall of the mixing chamber to inhibit the accumulation of solids and liquid in the mixing chamber.

In the operation of a fluidized bed polymerization reactor having distributor plate means positioned below said bed to provide both distribution of fluid and physical support for said bed; entry means at or near the base of said reactor for passage of fluid into said reactor; generally annular fluid

In the operation of a fluidized bed polymerization reactor having distributor plate means positioned below said bed to provide both distribution of fluid and physical support for said bed; entry means at or near the base of said reactor for passage of fluid into said reactor; generally annular fluid flow deflector means including aperture means associated with said entry means and a mixing chamber positioned between said distributor plate means and said entry means and wherein a fluid stream comprising a gas is continuously introduced into said reactor through said entry means, passed upward through said mixing chamber, through said distributor plate means and through said fluidized bed, the improvement which comprises providing said aperture means with sufficient size to allow passage of the fluidizing medium upwardly therethrough and dividing the entering fluid stream into at least two streams, a first stream flowing upward and outward in a fluid flow path peripherally between said aperture means and the wall of said mixing chamber and a second stream flowing in a central upward fluid flow path through said annular flow deflector means, the combined velocity and orientation of all fluid flow paths being capable of entraining and passing solid particles and liquid out of said mixing chamber through said distributor plate means and into said fluidized bed.
