| 摘要: |
Mo/Al2O3 catalyst was presulfided with (NH4)2S2O3 to elucidate presulfidation and activation mechanism. It is illustrated that the Mo oxide is firstly partially sulfided during presulfidation and then in situ reduced into MoS2？x in activation, and finally sulfided to active state during hydrodesulfurization (HDS). A synergistic effect between the S2？ and
S6+ ions in (NH4)2S2O3 produces a positive influence on the HDS performance. The S2？ ions contribute to the sulfidation of Mo ions |
