摘 要:乙烯是现代石化工业中最重要的原料之一。通过石油烃类蒸气裂解制备乙烯的同时会生成体积分数约为0.3%~3%的乙炔。这些微量乙炔会使乙烯聚合反应的催化剂中毒。乙炔选择性催化加氢被认为是脱除乙炔杂质的最有效方法之一。本文综述了乙炔选择性加氢的研究进展,介绍了乙炔加氢的反应机理,归纳总结了催化剂活性组分、助剂以及载体等对乙炔选择性加氢性能的影响。从电催化、光催化和光热催化的角度论述了如何进一步提高乙炔选择性加氢性能的发展趋势。最后对乙炔选择性加氢的后续研究提出一些建议。Ethylene is one of the most important raw materials in the modern petrochemical industry.The preparation of ethylene by steam cracking of petroleum hydrocarbons generates acetylene with a volume fraction about 0.3%to 3%.These trace amounts of acetylene can poison the catalyst of the ethylene polymerization reaction.Selective catalytic hydrogenation of acetylene is considered to be one of the most effective methods for removing acetylene impurities.This paper reviews the research progress of acetylene selective hydrogenation in recent years,introduces the reaction mechanism of acetylene hydrogenation,and summarizes the effects of catalyst active components,additives and carriers on the performance of acetylene selective hydrogenation.The development trend of how to further improve the performance of acetylene selective hydrogenation is discussed from the perspectives of electrocatalysis,photocatalysis and photothermal catalysis.Finally,some suggestions are proposed for the subsequent research on the selective hydrogenation of acetylene.
