Abstract: The current invention relates a process for making and using a bulk catalyst precursor (i.e. no support material is added as such) comprising Ni and Mo and/or W and an organic component, wherein the molar ratio of C:(Mo+W) ranges from 1.5 to 10. The bulk catalyst precursor is prepared from a mixture of metal-precursors with an organic agent. The organic agent is partly decomposed to form a mixed metal-oxide/C phase which is in effect the bulk catalyst precursor. This bulk catalyst precursor (i) is effectively insoluble in water (ii) does not have any appreciable pore volume or surface area and (iii) does not contain a (nano)crystalline metal-oxide phase as characterized by XRD.

Abstract: The precursor of a hydroprocessing catalyst is made by impregnating a metal oxide component comprising at least one metal from Group 6 of the Periodic Table and at least one metal from Groups 8-10 of the Periodic Table with an amide formed from a first organic compound containing at least one amine group, and a second organic compound containing at least one carboxylic acid group. Following impregnation heat treatment follows to form in situ generated unsaturation additional to that in the two organic compounds. The catalyst precursor is sulfided to form an active, sulfide hydroprocessing catalyst.
