Abstract
New sulfided metal catalysts are described, containing a metal X selected from Ni, Co and mixtures thereof, a metal Y selected from Mo, W and mixtures thereof, an element Z selected from Si, Al and mixtures thereof, and possibly an organic residue, obtained by the sulfidation of mixed oxide precursors, also new, having general formula (A) XaYbZcOd.pC (A) possibly shaped without a binder, or by sulfidation of mixed oxides having formula (A), in shaped form with a binder, wherein X is selected from Ni, Co and mixtures thereof, Y is selected from Mo, W and mixtures thereof, Z is selected from Si, Al and mixtures thereof, O is oxygen, C is selected from: a nitrogenated compound N, an organic residue deriving from the partial calcination of the nitrogenated compound N, said nitrogenated compound N, when present, being selected from: a) an alkyl ammonium hydroxide having formula (I) RIRIIRIIIRIVNOH (I) wherein the groups RI-RIV, the same or different, are aliphatic groups containing from 1 to 7 carbon atoms, b) an amine having formula (II) R1R2R3N (II) wherein R1 is a linear, branched or cyclic alkyl, containing from 4 to 12 carbon atoms, and R2 and R3, the same or different, are selecte…
