ABSTRACT:
Hydrocarbon feeds are upgraded by contacting a feed, at an elevated temperature and in the presence of hydrogen, with a 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 (NR.sub.4).sub.2 [M(WS.sub.4).sub.2 ], (NR.sub.4).sub.x [M(MoS.sub.4).sub.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.
