Resumen:
Catalysts PW(Mo)Ni/Al2O3(SiO2) were prepared from phosphotungstic or phosphomolybdic acids in dimethylformamide solutions. The characterization of the species present in the solutions and in the catalysts is shown. The performance of the catalysts for hydrodenitrogenation (HDN) and hydrodesulfurization (HDS) reactions are related to the precursor-support interaction and to the shape of concentration profiles in the pellets
