摘要： An apparatus for polymerizing olefins including a polymerization reactor and a vessel system for pre-activating a solid catalyst component, wherein the vessel system is arranged upstream of the polymerization reactor. The vessel system includes a contacting vessel which includes a main portion, a base portion, a head portion, an inlet, an outlet, and a stirrer positioned within the contacting vessel, wherein the ratio (H/D) of the height (H) of the main portion to the diameter (D) of the main portion is 1.8 or greater. The stirrer is located at a position between the inlet and the outlet.
