摘　　要：蒽醌加氢催化剂通常由载体和活性金属构成,分别从载体和活性金属两方面出发,综述了近年来蒽醌加氢催化剂关于载体制备及改性、活性金属的选择、负载方法、助剂添加等方面的研究进展。对比普遍使用的催化剂,经改性或添加助剂后的载体所制备的催化剂具有更高的活性和选择性。以Pd为活性金属,优化其负载工艺,可以得到高度分散的蒽醌加氢催化剂,以及通过添加第二金属,能够改善活性金属与载体的空间效应和电子效应,从而有效提高催化性能。优化载体性能和提高活性金属Pd的利用率,或寻求可替代金属将会是今后蒽醌加氢催化剂研究的重点方向。The catalyst of anthraquinone hydrogenation is generally composed of a carrier and an active metal.This article reviews the recent research progress of anthraquinone hydrogenation catalysts on the preparation and modification of supports,selection of active metals,loading methods,and addition of additives.According to the analysis,compared with the commonly used catalysts,the catalysts prepared by the modified or added additives have higher activity and selectivity.Taking Pd as the active metal and optimizing the loading process,the highly dispersed anthraquinone hydrogenation catalyst can be obtained.The addition of the second metal can effectively improve the catalytic performance through the electronic effect and morphologic effect.The optimization of the performance of the support,the improvement of the loading efficiency of the active metal Pd,and the search for alternative metals are the key directions for the future research of anthraquinone hydrogenation catalysts.
