摘要
概述了近年来乙炔氢氯化反应用低汞催化剂及无汞催化剂的研究与开发状况,重点对无汞金属催化剂(贵金属催化剂、非贵金属催化剂及多种金属组成的复合催化剂)和无汞非金属催化剂(杂原子掺杂的碳基催化剂、离子液体、氮化物等)的活性组分、催化机理及改性方法进行了总结和评述,并对这些催化剂的发展进行了展望.
Abstract
The research and development status of low-mercury catalysts and free-mercury catalysts for acetylene hydrochlorination in recent years was reviewed.The active components,catalytic mecha-nisms,and modification methods of mercury-free metal catalysts(precious metals catalysts,non precious metals catalysts,and multiple metals composite catalysts)and mercury-free non-metallic catalysts(carbon based catalysts doped with heteroatoms,ionic liquids,nitrides,etc.)were summarized and evaluated.The development of these catalysts was discussed.
