Ultra-deep hydrogen desulfurization multi-metal body catalyst with a stratified structure as well as preparation method and application thereof

The invention relates to an ultra-deep hydrogen desulfurization multi-metal body catalyst with a stratified structure. In the ultra-deep hydrogen desulfurization multi-metal body catalyst, metals include at last one VIII-group metal, at least one -valence metal and at least two VIB-group metals. The catalyst is characterized in that, counted by oxides and based on the catalyst, the catalyst comprises the following components by weight percent: 1%-50% of VIII-group metal, 1%-50% of -valence metals and 5%-60% of two VIB-group metals. The invention further discloses a preparation method and application of the catalyst. The catalyst is applied to the hydrogen desulfurization of diesel distillate containing 4,6-dimethyldibenzothiophene and expresses an ultra-high hydrogen desulfurization activity. According to the catalyst, the ultra-deep desulfurization is realized and the cost of the body catalyst is lowered.
