ABSTRACT OF THE DISCLOSURE Hydrocarbon feeds are upgraded by contacting a feed, at a elevated temperature and in the presence of hydrogen, with either a bulk or supported, self- promoted catalyst formed by compositing a porous, refractory inorganic oxide, support with one or more complex salts selected from the group consisting of (NR4)2[M(WS4)2], (NR4)x [M(moS4)2] and mixtures thereof wherein R is one or more alkyl groups, aryl groups or mixture thereof, wherein promoter metal M is covalently bound in the anion and is Ni, Co or Fe and wherein x is 2 if M is Ni and x is 3 if M is Co or Fe and heating said composite in a non-oxidizing atmosphere in the presence of sulfur and hydrogen and a hydrocarbon to form said supported catalyst. The bulk catalysts are formed in the absence of a support material.
