Abstract
The present invention relates to a method for oligomerizing olefins including the steps of: carrying out an oligomerization reaction of olefins by injecting an oligomerization transition metal catalyst, a cocatalyst, an olefin monomer and a solvent into a reactor; and injecting, into the reaction product of the oligomerization reaction, a catalyst inactivator including a gaseous inorganic material that contains oxygen.
