| Abstract: | The measurement of thiophene hydrodesulfurization(HDS)and pyridine hydrodenitrogenation activities is carried out in a fixed-bed reactor at a hydrogen pressure3.0MPa.The results show that the catalitic activity and stability of sulfided CoMo/(TiO2Al2O3)are superiored to molybdenum nitride on the reaction of thiophene hydrodesulfurization, but the HDN activity of Mo2N is obviously higher than that of sulfided CoMo/(TiO2-Al2O3).The disadvantage of Mo2N on thiophene hydrodesulfurization is due to the blockage of small pores in Mo2N particles by less dense MoS2,whereas the superiority of Mo2N onhydrodenitrogenation results from the adsorbsive behavior of pyridine on the surface ofMo2N. |
