Abstract: Methods for the oligomerization of ethylene, and more specifically, methods for the preparation of mainly ethylene oligomers of C10 or higher are described. A method can include 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. to produce ethylene oligomers of C10 or higher. The method for the preparation of ethylene oligomers can produce C8-16 ethylene oligomers in high yield without inducing deactivation of the catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.
