摘要： Disclosed are a process and system for preparing a catalyst slurry. The process can include preparing a catalyst slurry comprising a solid particulate catalyst and a carrier liquid in a catalyst slurry preparation system. The catalyst slurry preparation system can include a mixing vessel, a rotatable impeller system connected to the mixing vessel, and a motor connected to the rotatable impeller system. The rotatable impeller system can include an agitator shaft and a hub connected to the agitator shaft. The hub and at least a portion of the agitator shaft are positioned within the mixing vessel along a longitudinal axis of the mixing vessel, and the hub has at least three blades.

摘要： A reactor for the polymerization of olefins comprising a first inlet for introducing a first stream comprising monomer(s), catalyst(s) and optionally hydrogen, solvent or comonomer(s) and/or mixtures thereof, at least one outlet for withdrawing a product stream, characterized in that the reactor further comprises at least one second inlet for introducing a second stream comprising monomer(s), catalyst(s) and optionally hydrogen, solvent or comonomer(s) and/or mixtures thereof; and a process for polymerizing olefins in a reactor according to the present invention, comprising the steps of introducing monomer(s), catalyst(s), and optionally hydrogen, solvent or comonomer(s) and/or mixtures thereof as the first stream via the first inlet into the reactor forming a reaction mixture; polymerizing a polymer from the reaction mixture; withdrawing the product stream via the at least one outlet from the reactor; characterized in that the process comprises a further step of introducing a second stream comprising monomer(s), catalyst(s), and optionally hydrogen, solvent or comonomer(s) and/or mixtures thereof into the reactor via the at least one second inlet into the reactor.
