Abstract
Provided is a method for oligomerization of ethylene, and more particularly, a method for producing 1-hexene and 1-octene at a high selectivity under an ethylene atmosphere by inducing a remarkably improved catalytic activity while effectively reducing a production amount of polyethylene by introducing the oligomerization catalyst and a cocatalyst mixture containing at least two aluminums together and adjusting the kind of oligomerization catalyst and injection conditions thereof.
