Method for supplying granulated material to a polymerisation reactor |
摘要 |
The present invention relates to methods for delivering granulated material to a reactor for use in the polymerization of alpha-olefin comprising the steps of: providing a first conduit having a granulated material inlet, the conduit being operably connected to a pocket ball valve comprising at least one pocket, said pocket ball valve being operably connected to a second conduit, said second conduit being operably connected to a polymerization reactor; introducing a granulated material to the first conduit through said inlet; metering the granulated material through the pocket ball valve; and passing said material through the second conduit to the polymerization reactor. The present invention also relates to polyolefin production processes and polyolefin producing units.
