Claim:
1. A method for hydrotreating hydrocarbon feedstocks, said method comprising contacting a hydrocarbon feedstock under hydroprocessing hydrotreating conditions with a bulk catalyst composition comprising bulk metal particles, wherein said bulk metal particles are made by a process comprising: (i) combining and reacting, in a reaction mixture comprising a protic liquid, at least one compound containing a Group VIII non-noble metal and at least one compound containing a Group VIB metal, the at least one Group VIII non-noble metal comprising Ni, in the presence of (ii) added dispersable nanoparticles consisting essentially of laponite having a dimension of less than 1 μm and a smallest dimension of less than 5 nm when dispersed in the protic liquid to form bulk metal particles; (iii) calcining the bulk metal particles to convert said compound containing a Group VIII non-noble metal and said compound containing a Group VIB metal to their metal oxide forms; wherein: the combined weight of Group VIII non-noble metal and Group VIB metal (i) in said bulk metal particles, calculated as weight of metal oxides relative to the total weight of bulk metal particles, represents from 50 wt. % to 99.5 wt. % of the total weight of the bulk metal particles; the weight of nanoparticles (ii) in said bulk metal particles represents from 0.5 wt. % to 10 wt. % relative to the total weight of metal oxides and nanoparticles; and the hydrodesulfurization activity of the bulk catalyst composition containing laponite is greater than a catalyst composition with the same metal content that does not contain laponite.
