METHOD OF SPLITTING THE RETURN FLUIDIZATION GAS IN A GAS SOLIDS OLEFIN POLYMERIZATION REACTOR

摘要

The present invention relates to a process for polymerizing olefin monomer(s) in a gas solids olefin polymerization reactor wherein the fluidization gas is split and returned to the reactor into the bottom zone of the reactor and directly into the dense phase formed by particles of a polymer of the olefin monomer(s) suspended in an upwards flowing stream of the fluidization gas in the middle zone of the reactor.
