本发明公开了种乙烯齐聚催化剂组合物，包括下式(I)所示的氯化2-异丁酰基-1,10-菲咯啉缩胺合铁(II)配合物作为主催化剂、含铝助催化剂、水和有机溶剂，式中，R-R各自独立地选自氢、C-C烷基、卤素、C-C烷氧基和硝基。利用本发明提供的齐聚催化剂组合物和方法用于乙烯齐聚，能够克服了技术偏见，优化了齐聚反应工艺，不仅齐聚活性高，助催化剂用量低，而且使乙烯齐聚反应工艺引发迅速、运行稳定，催化效果和成本得到较好的平衡，实用性强，使得乙烯齐聚反应成本大幅下降，综合考虑催化效果和生产成本，工业化前景广阔。 The invention discloses a catalyst composition for ethylene oligomerization. The catalyst composition comprises chlorinated-2-isobutyryl-1,10-phenanthroline amine iron (II) which is shown in a formula (I) as described in the specification and is used as a main catalyst, an aluminum-containing cocatalyst, water and an organic solvent. In the formula (I), R1 to R5 are independently selected from the group consisting of hydrogen, C1-C6 alkyl groups, halogen, C1-C6 alkoxy groups and a nitro group. With the oligomerization catalyst composition and method provided by the invention for ethylene oligomerization, technical biases are overcome, ethylene oligomerization process is optimized, high oligomerization activity is obtained, the application amount of the cocatalys
