Abstract

A nozzle for catalyst injection for olefin polymerization is provided. In one or more embodiments the nozzle includes a first conduit including a body, a tapered section, and an injection tip. The nozzle also includes a second conduit having an inner surface and an outer surface. The first conduit is disposed about the second conduit defining a first annulus therebetween. The nozzle further includes a support member at least partially disposed about the outer surface of the first conduit defining a second annulus therebetween. The support member has a converging outer surface at a first end thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Application Serial No. 60 / 848,910, filed October 3, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the invention generally relate to nozzles for catalyst injection and methods of using the same. More particularly, embodiments of the present invention relate to foaming nozzles for catalyst injection used in polyolefin production and methods of manufacturing the same. Background technique [0004] Liquid catalysts used in gas phase polymerizations offer many advantages over traditional solid-supported catalysts. For example, liquid catalysts require less equipment and raw materials to produce. Liquid catalysts also contribute fewer impurities to the final polymer product. Furthermore, the activity of liquid catalysts is not affected by the surface area of ​​the supporting material. US Patent No. 5,317,036 discloses more det...
