ABSTRACT:
A novel aqueous solution for the one step impregnation of catalytic supports, catalysts prepared from such solution, and the preparation and the use of catalysts prepared thereby. The catalysts prepared are used in the hydrotreatment of petroleum fractions and particularly in hydrodesulfurization and/or denitrogenization. The solution is a combination of at least one compound of a metal from group IVa (e.g. Zr), at least one compound of a metal from group VIa (e.g. Mo or W), at least one compound of a metal from group VIII (e.g. Co or Ni), and at least one water soluble amine (e.g. ethylenediamine or MEA).
