METHOD FOR OLIGOMERIZATION OF ETHYLENE

摘要

The present invention relates to a method for oligomerization of ethylene, comprising the steps:
a) feeding ethylene, solvent and a catalyst composition comprising catalyst and cocatalyst into a reactor,
b) oligomerizing ethylene in the reactor,
c) discharging a reactor effluent comprising linear alpha-olefins including I-butene, solvent, unconsumed ethylene dissolved in the reactor effluent, and catalyst composition from the reactor,
d) separating ethylene and 1-butene collectively from the remaining reactor effluent, and
e) recycling at least a part of the ethylene and the 1-butene separated in step d) into the reactor.
