  • HYDROCYCLONE MODIFICATION OF CATALYST SYSTEM COMPONENTS FOR USE IN OLEFIN POLYMERIZATION
    Publication number: 20230356206
    Abstract: Methods for modifying a catalyst system component are disclosed in which a feed mixture containing a fluid and from 1 to 15 wt. % of a catalyst system component is introduced into an inlet of a hydrocyclone, an overflow stream containing from 0.1 to 5 wt. % solids and an underflow stream containing from 10 to 40 wt. % solids are discharged from the hydrocyclone, and the underflow stream is spray dried to form a modified catalyst component. Often, from 4 to 20 wt. % of the catalyst system component in the feed mixture has a particle size of less than or equal to 20 ?m, or less than or equal to 10 ?m.
    Type: Application
    Filed: July 25, 2023
