Abstract
Methods for the oligomerization of ethylene, and more specifically, methods for the preparation of mainly ethylene oligomers of Cor 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 Cor higher. The method for the preparation of ethylene oligomers can produce Cethylene oligomers in high yield without inducing deactivation of the catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.
