摘　　要：综述了国内外近几年乙烯齐聚制α-烯烃多相催化剂的研究进展。从多相催化剂的种类、活性中心、金属离子的种类、价态、配位形态和助催化剂作用等方面深刻揭示了多相催化剂对乙烯齐聚的反应性能,并对催化剂的结构与性质、反应中间体的形成及反应机理进行了论述。提出了多相催化剂研究存在的问题,并指出了今后多相催化剂研究开发的主要方向。Recent advances in heterogeneous catalysts of ethylene oligomerization to α-olefins is summarized. The reaction performance of ethylene oligomerization is reviewed from the aspects of catalysts, active site, the varieties, valent state, coordination state of metal cation, the roles of co-catalysts. The structure and characteristics of heterogeneous catalysts, formation of intermediates in the reaction and reaction mechanism are discussed. The main problems in researching heterogeneous catalysts are indicated. Future development of heterogeneous catalysts in ethylene oligomerization to α-olefins is presented.
