摘要：

Ethylene is one of the most important industrial raw materials in petrochemical industry, however, the presence of a small amount of acetylene impurities in ethylene products will directly affect the subsequent application of ethylene. Selective catalytic hydrogenation of acetylene is considered to be one of the most effective methods for removing acetylene impurities. In this paper, the research progress of acetylene selective hydrogenation catalysts in recent years is reviewed, including the reaction mechanism, and the effects of active components, promoters, supports and structures on the catalyst performance. In view of the fact that the Pd-based catalysts are still the mainstream catalysts used in industry, the research status and current challenges of Pd-based catalysts are reviewed, and suggestions for the optimization of catalytic performance are proposed. Finally, the development trends to further improve the catalytic performance of acetylene hydrogenation catalysts are summarized, mainly from the aspects of single-atom alloy catalyst, catalyst micro-control, and electrochemical olefin hydrogenation. © 2022 Chemical Industry Press.
