随着炼化一体化以及煤化工的快速发展，碳四（C₄）副产资源大幅增长，而丁二烯选择性加氢技术是实现C₄馏分高值利用的关键；然而，在丁二烯选择性加氢反应生成1-丁烯的过程中，还会伴随2-丁烯、丁烷等副产物生成。因此，开发高活性、高选择性的催化剂是本领域最重要的研究内容。介绍了近年来丁二烯选择性加氢催化剂的设计、制备以及应用情况，总结了一些改进催化剂性能的策略，并对过渡金属基丁二烯选择性加氢催化剂的前景进行了展望。

With the integration of refining and chemical industries and the rapid development of coal chemical industry, the amount of C₄ by-product resources has grown substantially.Selective butadiene hydrogenation technology is the key to realize the appreciation and utilization of C₄ fractions.However, the selective hydrogenation of butadiene to produce 1-butene will also accompany with the formation of by-products such as 2-butene and butane.Therefore, the development of catalysts with high activity and selectivity is the most important research content in this field.The design, preparation and application of the catalysts for selective butadiene hydrogenation in recent years are introduced.Several strategies for optimizing catalyst performance are summarized, and the application prospects of transition metal-based catalysts for selective butadiene hydrogenation are discussed.
