  The present invention relates to a novel linear a-olefin catalyst composition, and preparation and use thereof. The catalyst composition includes a main catalyst and a co-catalyst, wherein the main catalyst is an imino-based iron coordination compound, and the co-catalyst is a mixture of methylaluminoxane, triisobutylaluminum, and borane or GaCl 3 . The catalyst composition can be used to catalyze ethylene oligomerization to produce linear α-olefins having a selectivity of greater than 96%, carbon distribution between C4-C28 with the component of C6-C20 being greater than 75%. The catalyst of the invention is stable in structure and can be used for ethylene oligomerization with high catalytic efficiency. The method of the invention has the advantages of relatively convenient in operation, readily available of raw materials, high yield, low costs, less pollution and easy for industrial production.

  本发明涉及一种新型的线性α-烯烃催化剂组合物，以及其制备和使用。该催化剂组合物包括主催化剂和辅助催化剂，其中主催化剂是一种基于亚胺的铁配位化合物，而辅助催化剂是甲基铝氧烷、三异丁基铝和硼烷或氯化镓的混合物。该催化剂组合物可用于催化乙烯寡聚反应，产生选择性大于96%的线性α-烯烃，碳分布在C4-C28之间，其中C6-C20的组分大于75%。该发明的催化剂结构稳定，可用于高效乙烯寡聚反应。该发明的方法具有操作相对便利、原料易得、产量高、成本低、污染少且易于工业生产的优点。
