Abstract: The present invention relates to a method for the oligomerization of ethylene, and more specifically, to a method for the preparation of mainly ethylene oligomers of C10 or higher, which comprises obtaining mainly ethylene oligomers of C4 or higher by performing a first oligomerization of an ethylene gas using a Ni-containing mesoporous catalyst, followed by a second oligomerization using an ion exchange resin, etc. The method for the preparation of ethylene oligomers according to the present invention can produce C8-16 ethylene oligomers in high yield without inducing inactivation of a catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.
