Catalyst composition and process for ethylene oligomerization
The present disclosure provides a catalyst composition for ethylene oligomerization including an imino ferrous complex shown in Formula (I) as the main catalyst, an aluminum-containing cocatalyst, water, and an organic solvent:According to the present disclosure, a higher oligomerization activity can be obtained with the catalyst composition than with a catalyst composition system in the prior art which contains no water. Moreover, when the catalyst composition according to the present disclosure is used, a high selectivity of α-olefins is obtainable. Besides, the catalyst composition according to the present disclosure can enable rapid initiation, stable operation, and good repeatability of the oligomerization reaction. According to the present disclosure, a high oligomerization activity can be obtained even at a rather low ratio of Al/Fe, or at a low reaction temperature.
