FIELD: chemistry.

SUBSTANCE: description is given of a catalytic composition with general formula, in consideration of oxides: (X)_b(M)_c(Z)_d(O)_e (I), in which X represents at least one group VIII base metal, M represents at least one group VIB metal, Z represents one or more elements, chosen from aluminium, silicon, magnesium, titanium, zirconium, boron and zinc, O represents oxygen, one of b and c represents an integer 1, and d, e and one of b and c represents each a number bigger than 0, such that the molar ratio b:c ranges from 0.5:1 to 5:1, molar ratio d:c ranges from 0.1:1 to 50:1, and molar ratio e:c ranges from 3.6:1 to 108:1. The method of obtaining the composition involves heating a composition with general formula (NH₄)_a(X)_b(M)_c(Z)_d(O)_e (II), in which a represents a number bigger than 0, and X, M, Z, O, b, c, d and e are such that, they are bigger, at temperature ranging from 100 to 600°C, where the composition with formula II is in suspension form or is extracted from a suspension, optionally after maturing at temperature ranging from 20 to 95°C for a period of not less than 10 min. The above mentioned suspension is obtained by precipitation at temperature and within a period of time, sufficient for obtaining formula II composition, of at least one compound of a group VIII base metal at least one compound of a group VIB metal at least one refractory oxide material and alkaline compound in protonic liquid. At least one of the metal compounds is partially in solid state and partially in dissolved state. Description is given of volumetric metal oxide catalytic composition, obtained using the method given above, and a composition with general formula I, which can be obtained using a precipitation method, in which a refractory oxide material in quantity ranging from 15 to 40 wt % is precipitated at least with one compound of a group VIII base metal, and at least with one compound of a group VIB metal, as well as the method of obtaining it. Description is also given of the use of compositions, moulded or sulphided when necessary, in hydro-processing.

EFFECT: increased activity of catalytic compositions.
