摘　　要：简述了近些年来有机配体对加氢处理催化剂的影响研究情况。添加有机配体可以提高加氢处理催化剂活性,从有机配体对加氢处理催化剂的制备及硫化过程的影响角度对文献的研究结果进行了综述,并对有机配体的作用机理进行了分析讨论。文中总结指出,有机配体与活性金属、载体的作用改变了金属与载体的相互作用,影响了金属组分的分散和硫化,从而有利于高活性CoMoS相的生成。The effect of organic ligands on hydrotreating catalysts and catalysis are reviewed.The organic ligands enhance the activity of hydrotreating catalysts.The mechanisms of organic ligands are discussed from two points of the preparation of catalyst and the sulfidation step.Organic ligands will interact more strongly with the metal species and the support.They prevent the strong metal-support interactions,and impact the dispersion and sulfidation of the metal species.Therefore,the more active type CoMoS phases can be formed.
