Process for supplying catalyst to a polymerization reactor |
| abstract |
The present invention relates to a method for feeding metallocene catalyst slurry to an olefin polymerization loop reactor ( 1 ) using a positive displacement device ( 5 ) positive displacement device comprising a first chamber and a second chamber, each chamber having an inlet and an outlet and each chamber comprising an ball arranged between the walls of said chamber, wherein said chambers are connected to each other by a pump chamber operably connected to a pump, wherein, the difference between the diameter of said ball and the diameter of said chamber is comprised between 5 to 200 times the average particle size (d50) of said catalyst. |
