FIELD: chemistry.
SUBSTANCE: developed is a highly active trimetallic material containing mixed transition metal oxide and a method for production thereof. The material can be subjected to sulphidation producing metal sulphides used as a catalyst in a method for conversion, e.g., in hydrotreatment. Hydrotreatment can include hydrodenitrification, hydrodesulphurisation, hydrodemetallisation, hydrodesilication, hydrodearomatisation, hydroisomerisation, hydrorefining, hydrogenation purification, and hydrocracking. The material for preparing the catalyst comprises a mixed transition metal oxide with the formula: (MIa)m(MIIb)n(MIIIc)oOeq, wherein MI constitutes a metal or a mixture of metals selected from group VIII (group 8, 9 and 10 according to IUPAC); MII constitutes a metal selected from group VIB (group 6 according to IUPAC); MIII constitutes a metal selected from group VIB (group 6 according to IUPAC), different from MII; a, b, c, and e constitute the valence state of MI, MII, MIII and O; m, n, o, and q constitute the molar ratio of MI, MII, MIII, and O, wherein m/(n + o) equals 1/10 to 10/1, wherein n/o > 0 and 0 ≤ o/n ≤ 100, wherein q is greater than 0; and wherein a, b, c, e, m, n, o, and q satisfy the equation: a × m + b × n + c × o + e × q = 0, wherein the mixed transition metal oxide is characterised by an X-ray diffraction pattern containing the peaks visualised in Table A: Table A, 2θ (°) - d (Å) - 100 (I/Io); 8 to 14 - 6.320 to 11.043 - very weak; 34.5 to 36.5 - 2.460 to 2.598 - very strong; 53 to 55 - 1.668 to 1.726 - strong to very strong; 55 to 58 - 1.589 to 1.668 - weak to average; 58.5 to 62.5 - 1.485 to 1.576 - very weak; 62.8 to 63.8 - 1.458 to 1.478 - average; wherein the peak between the values of 2 θ(°) at 55 to 58 has a full width at the level of half of the maximum of more than 3°.
EFFECT: high activity of the hydrotreatment catalyst.
