AI Technical Summary

Problems solved by technology

Polymers produced outside the reactor can have very bad properties due to completely different temperatures and gas compositions at some points in the recovery system
Although a minor fraction of total polymer production, fines returned to the reactor can significantly affect overall product suitability

Abstract

A process for the polymerization of olefin's, including: introducing an olefin and a polymerization catalyst into a polymerization reactor to form a polyolefin, the polymerization reactor including: a fluidized bed region having a top and a bottom; and a motive bed region; wherein a first end of the motive bed region is fluidly connected to the top of the fluidized bed region; and wherein a second end of the motive bed region is fluidly connected to the bottom of the fluidized bed region; and wherein a diameter of the fluidized bed region is greater than a diameter of the motive bed region; circulating at least a portion of the olefin, the catalyst, and the polyolefin through the fluidized bed region and the motive bed region; maintaining a dense-phase fluidized bed within the fluidized bed region; recovering polyolefin from the fluidized bed region, is provided. A reactor system directed to the process is also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Serial No. 61 / 125,069, filed April 22, 2008, the disclosure of which is incorporated by reference in its entirety. technical field [0003] Embodiments disclosed herein relate generally to reactor systems and continuous polymerization processes using gas phase polymerization reactors. More specifically, embodiments disclosed herein relate to semi-circulating fluidized bed reactor systems and methods of using the same. Other embodiments disclosed herein relate to methods of producing polyolefins and polyolefin copolymers using semi-circulating fluidized bed reactors. Background technique [0004] It is known that many polymers can be produced in powder form in fluidized bed reactors in which fluidization is provided by a circulating mixed gas comprising one or more monomers. For example, gas phase polymerization is a common process widely used in the production of polyolefins (eg, ...
