METHOD FOR THREE-PHASE POLYMERIZATION OF ALPHA-OLEFIN USING THREE-PHASE FLUIDIZED BED

摘要

PURPOSE: A tertiary polymerization method of alpha-olefins is provided to cause turbulent mixing between a catalyst and reactant by bubble shaking and to ensure uniform heat transmission through whole reactors. CONSTITUTION: A tertiary polymerization method of alpha-olefins comprises the steps of: supplying liquid stream to a reaction region(flowing layer)(110) of a tertiary fluidized bed reactor(100); supplying gas stream to the lower part(130) of the tertiary fluid bed; forming a poly phase (three-phase) reaction medium by injecting the liquid stream to the reaction region and polymerizing the polyolefin with alpha-olefin; and discharging the polyolefin polymer from the tertiary fluidized bed reactor.
