Zusammenfassung:	The present invention relates to an ultra-deep hydrodesulfurization multi-metal bulk catalyst of a layered structure. Metals in the multi-metal bulk catalyst consist of at least one VIII family metal, at least one +2 metal, and at least two VIB family metals. As reduced to oxides and based on the catalyst, the catalyst comprises the VIII metal of 1-50 weight%, the +2 metal of 1-50 weight%, and the two VIB family metals of 5-60 weight%. Also disclosed are a preparation method and application of the catalyst. The present invention shows the extremely high hydrodesulfurization activity when used in hydrodesulfurization of a diesel fraction containing 4,6-dimethyl dibenzothiophene, realizes ultra-deep hydrodesulfurization, and reduces the costs of the bulk catalyst. La présente invention concerne un catalyseur multi-métallique massique à structure en feuillets pour une hydrodésulfuration ultra-profonde. Les métaux du catalyseur multi-métallique massique comprennent au moins l'un des métaux du groupe VIII, au moin
