The novel Al2O3 synthesis by mechanochemical activation of aluminum nitrate hydrate was applied to prepare hydrodesulfurization (HDS) NiMo catalysts. Impregnation techniques using the complex made by dissolution of nitrilotriacetic acid (NTA), ammonium heptamolybdate and nickel nitrate and the Anderson-type heteropolyoxymolybdate ((NH4)4Ni(OH)6Mo6O18) complex were compared with conventional impregnation using subsequent deposition of ammonium heptamolybdate (first) and nickel nitrate (second) with calcination in between. Properties of the support and HDS catalysts were studied by N2 physisorption, Raman spectroscopy, H2 temperature-programmed reduction (H2-TPR), O2 chemisorption and X-ray photoelectron spectroscopy (XPS).
