METHOD FOR OLIGOMERIZATION OF ETHYLENE AND REACTOR SYSTEM THEREFOR WITH REMOVAL OF HEAVY MOLECULAR WEIGHT OLIGOMERS

摘要

The present invention relates to a method for oligomerization of ethylene to form linear alpha- olefins in an oligomerization reactor in the presence of solvent and catalyst, wherein a reaction product containing heavy molecular weight oligomers (HMWO) is discharged from the oligomerization reactor and is passed to and filtrated in a filtration unit, characterized in that the filtration residue of HMWO is removed from the filtration unit discontinuously via a discharge valve; and to a reactor system therefore.
