摘　　要：主要阐述了铬系催化剂在乙烯选择性三聚制1-己烯方面的研究进展,总结了目前工业化进程中仍然存在的问题,并展望了该领域未来的发展方向。指出乙烯三聚高选择性制1-己烯,因其具有产物单一易分离、流程简单、耗能低等优点,正逐渐替代传统生产1-己烯的费托合成法和非选择性齐聚法。The research progress on chromium-based catalysts in the selective trimerization of ethylene to 1-hexene was mainly introduced.And some shortcomings in the current industrialization process were analyzed.Moreover,the future development directions in this field were investigated.It was pointed out that the highly selective trimerization of ethylene had gradually replaced the traditional Fischer-tropsch synthesis and non-selective oligomerization methods in the 1-hexene production at present,due to its obvious advantages on the easy seperation of the single product,the simple technical process and the lower energy consumption.
