钴或镍在加氢脱硫(HDS)催化剂中的助剂作用文献已有很多的讨论。近年来,研究结果发现,少量的钌加入到Mo/Al_2O_3和Co-Mo/Al_2O_3催化剂上可以显著地提高其加氢脱硫活性,可是关于钌的助剂作用前人研究的较少。因此对比研究钴和钌的的助剂作用有助于认识各种不同类型的助剂在加氢脱硫催化剂中的功能。本文应用程序升温还原方法对钴和钌在加氢脱硫催化剂的前身态氧化物还原过程中的助剂作用进行了考察。
There has been much discussion of the role of cobalt or nickel as a builder in hydrodesulfurization (HDS) catalysts. In recent years, the results show that a small amount of ruthenium added to the Mo / Al 2 O 3 and Co-Mo / Al 2 O 3 catalysts can significantly improve its hydrodesulfurization activity, but less research on the role of ruthenium additives. Therefore, a comparative study of cobalt and ruthenium additives helps to understand the different types of additives in the hydrodesulfurization catalyst function. In this paper, the effects of cobalt and ruthenium on the role of promoters in the reduction of precursor oxide of hydrodesulfurization catalysts were investigated by the temperature-programmed reduction method.
