The effect of diethylene glycol addition on the formation of oxide precursors of nickel–molybdenum sulfide hydrotreating catalysts was studied by Raman spectroscopy and differential dissolution. The NiMoP/Al2O3 catalyst was prepared by impregnation of γ-alumina with an aqueous solution obtained by successive dissolution of H3PO4, MoO3, and Ni(OH)2 in water. To prepare the NiMoP-diethylene glycol/Al2O3 catalyst, diethylene glycol was added to the impregnation solution. On contact of the impregnation solution with γ-alumina, the HxP2Mo5O23(6−x)− heteropolyanions initially present in the solution decompose to form polymolybdates. Without organic additive, the heptamolybdate anion (Mo7O246−) is formed, whereas the use of diethylene glycol leads to the formation of polymolybdates of different structures, mainly with high degree of polymerization. In contrast to Mo7O246−, such polymolybdates are probably incapable of interacting with the support surface to generate aluminum molybdates that do not form the most active “NiMoS” phase.
