Title:
GAS-PHASE PROCESS FOR THE POLYMERIZATION OF ALPHA-OLEFINS
Document Type and Number:
WIPO Patent Application WO/2009/077185
Kind Code:
A8
Abstract:
A continuous gas-phase process for the polymerization of alpha-olefins, in particular ethylene, comprising passing an alpha-olefin monomer stream through an oil filter in order to reduce the amount of oil to less than 8 ppm, and polymerizing the thus purified monomer feed in gas-phase reactor; the reduction of the amount of oil improves the operability of the plant over time.
