FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst which includes a substrate containing at least one solid crystalline IZM-2, the X-ray diffraction pattern of which includes spectral lines recorded in the table below:

where FF = very intense; F = intense; m = average; mf = moderately weak; f = weak; ff = very weak, and having a chemical composition expressed on an anhydrous base, in terms of oxide moles, having the following general formula: XO₂: aY₂O₃:bM₂/_nO, wherein X represents at least one tetravalent element, Y represents at least one trivalent element and M is at least one alkali metal and/or an alkali-earth metal of valency n, a and b representing respectively the number of moles of Y₂O₃ and M₂/_nO, and a is between 0 and 0.5 and b is between 0 and 1, and an active phase containing at least one hydro-dehydrogenating element from group VIB and/or at least one hydrogenating-dehydrogenating element from group VIII and/or at least one hydrogenating-dehydrogenating non-noble element of group VIII of the periodic table, said catalyst being a sulphide phase catalyst. The invention also relates to hydrocracking, hydrofining and hydroconversion methods where said catalyst is used.

EFFECT: obtaining a catalyst with catalytic properties in conversion processes.
