| Abstract: |
| A novel preparation method of diesel oil deeply-hydrotreating catalysts was introduced. By using ammonium tetra-thiomolybdate, ammonium tetrathiotungstate and basic nickel carbonate as the catalyst precursors and compound MS-1 as the template unsupported Ni-Mo-W sulfide catalysts with higher specific surface area，proper pore volume and mesoporous structure were synthesized through the technology of low temperature solid-state surface reaction. The X-ray diffraction ( XRD), low temperature N2 adsorption ( BET method)，scanning electron microscopy ( SEM) and high resolution transmission electron microscope ( HRTEM) were employed to characterize the as-synthesized sulfide catalysts. The as-synthesized catalysts were evaluated in the high-pressure vessel by utilizing FCC diesel oil as the material. The evaluation results show that the as-synthesized sulfide catalysts have excellent performance of hydrodesulfurization and hydrodenitrogenation. |
