摘　　要：对各种苯乙炔选择性加氢催化剂的开发研究情况进行了详细介绍。由于负载型钯催化剂和镍催化剂在加氢反应领域应用广泛,本文对这两种催化剂进行了重点介绍。阐述了各种催化剂的性能、使用条件、存在的主要问题、失活原因以及改进措施。提出今后对苯乙炔选择性加氢催化剂的改进应以高空速、适当提高操作温度、改善对原料的适应性等为目标。The development and research of several catalysts for selective hydrogenation of phenylacetylene (PA) are introduced in details. Since the supported palladium catalysts and nickel catalysts are extensively used in many hydrogenation processes, more particular attention is paid to these two kinds of catalysts. The performances and work conditions of the catalysts, the problems existed, the properties of deactivation and its method of improvement are presented. It is pointed out that, the future improvement of PA selective hydrogenation catalyst should be aimed at high space velocity; relative higher temperature and good adaptability to raw materials.
