FIELD: chemistry.

SUBSTANCE: invention relates to mixed oxides of transition metals and based on them sulphided metal catalysts. Claimed are mixed oxides, which have general formula X_aY_bZ_cO_d·pC (A), possibly formed without binding agent, where X is selected from Ni, Co and their mixtures, Y is selected from Mo, W and their mixtures, Z is selected from Si, Al and their mixtures, O represents oxygen, C represents organic residue, obtained as a result of partial calcination of nitrogen-containing compound N, selected from a) alkylammonium hydroxide, which has formula (I): R^IR^IIR^IIIR^IVNOH(I), in which groups R^I-R^IV are similar or different aliphatic groups, containing from 1 to 7 carbon atoms, b) amine of formula (II): R¹R²R³N(II), in which R¹ is linear, branched or cyclic alkyl, containing from 4 to 12 carbon atoms, and R² and R³, similar or different, are selected from H and linear, branched or cyclic alkyl, containing from 4 to 12 carbon atoms, with said alkyl being the same alkyl as R¹, or different from it; a, b, c, d are numbers of moles of elements X, Y, Z, O respectively; p is weight percent portion of C relative to the total weight of precursor of formula (A); a, b, c, d are larger than 0; a/b is larger or equals 0.3 and is smaller or equals 2; (a+b)/c is larger or equals 0.3 and is smaller or equals 10, preferably constituting from 0.8 to 10, d=(2a+6b+Hc)/2, where H=4, if Z=Si, and H=3, if Z=Al; and p is larger or equals 0 and is smaller or equals 40%. Versions of method for preparation of claimed oxides are also claimed.

EFFECT: catalysts, based on said mixed oxides, are efficient in methods of hydropurification, in particular in simultaneous realisation of hydrosulphurisation and hydrodenitrogenation.
