Abstract
The invention discloses a multi-metallic bulk catalyst with layered structure, wherein the metals in the multi-metallic bulk catalyst is consisted of a Group VIII metal M, at least one metal Mwith the valence of +3 and at least two Group VIB metals M+M, wherein (the mole number of M+the mole number of M):(the mole number of M+the mole number of M) is from 1:9 to 9:1; the mole number of M:the mole number of Mis from 1:5 to 5:1; and the mole number of M:the mole number of Mis from 1:5 to 5:1. The invention also discloses the preparation method and use of the above catalyst. The invention is use for the hydrodesulfurization of diesel distillate including 4,6-dimethyldibenzothiophene, wherein the catalyst exhibits a extreme high hydrodesulfurization activity. Thus, the ultra-deep hydrodesulfurization is achieved and the cost of the bulk catalyst is reduced.
