Graded Preparation and Industrial Applications of Large-Ball Polyolefin Catalyst Carriers

In the process of preparing polyolefin catalyst carrier, particle size is often unqualified because adhesion smaller particles to each other and crushing effect mechanical vibration. To improve output target products, reduce loss, yield, a high-precision high-efficiency carrier classification was developed according embedded principle. The hydraulic hydrocyclone equipment designed in this work could eliminate short-circuit flow achieve good integration internal field, thereby enhancing separation accuracy high efficiency. successfully applied industry with smooth operation. large-ball prepared by grading showed small distribution coefficient, excellent polymerization performance, average graded large ball support 65–75 μm SPAN < 0.7, which meet needs DQC700 series products.
