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 XYZO·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): RRRRNOH(I), in which groups R-Rare similar or different aliphatic groups, containing from 1 to 7 carbon atoms, b) amine of formula (II): RRRN(II), in which Ris linear, branched or cyclic alkyl, containing from 4 to 12 carbon atoms, and Rand R, 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 R, 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.31 cl, 21 ex |
