Claim 0:
1. A process of hydrotreating of a feed containing one or more hydrocarbons which comprises contacting the feed with hydrogen in the presence of a metal sulphide catalyst obtained by sulphidation of a precursor which is in the form of a mixed oxide of formula (I) or of a mixed oxide of formula (I) bound to an inorganic binder B, wherein formula (I) is as follows:

MeaNibMocWdAlcOf·pC  (I),

wherein:
Me is at least one selected from the group consisting of Zn, Cd, Mn, and a mixture thereof,
C comprises a polymer organic compound,
a is higher than or equal to 0,
b, c, d, e and f are higher than 0,
f is equal to (2a±2b+6c+6d+3e)/2,
a (a+b)/(c+d) ratio is 0.9 to 1.1,
an a/b ratio is 0 to 1.5,
a c/d ratio is 0.2 to 5,
an (a+b+c+d)/e ratio is 0.6 to 5, and
p is a weight percentage of the polymer organic compound C and optionally a residue of the polymer organic compound C, with respect to a total weight of the mixed oxide of formula (I), and is higher than 0.2% and lower than or equal to 40%, and
the mixed oxide of formula (I) comprises an amorphous phase and a pseudo-crystalline phase isostructural to Wolframite.
