| Abstract: | The Ru-Fe/ZrO2 catalysts were prepared by precipitation method for partial hydrogenation of benzene to cyclohexene,in which ruthenium was an active component,iron was a promoter and ZrO2 was a dispersant.The influences of the different contents of Fe,Ru/ZrO2 ratio,catalyst precipitation temperature and stablity on the catalytic characteristics were studied.The results indicate that when the Fe/Ru ratio is 16% and Ru/ZrO2 ratio is 14% at 80 ℃ the synthetically catalytic characteristics of Ru-Fe/ZrO2 is the best,and the benzene conversion and cyclohexene selectivity reach 34.70% and 77.52%,respectively.XRD shows that the active component Ru is highly dispersed. |
