FIELD: chemistry. ^ SUBSTANCE: invention relates to promoter catalysts on a combined zeolite/aluminosilicate substrate with low content of macropores and to methods of hydrocracking/hydroconversion and hydrofining, in which said catalysts are used. The catalyst contains at least one hydrogenating-dehydrogenating element, selected from a group comprising group VIB and group VIII elements, a promoter element in a controlled amount, selected from phosphorus oxide, and a substrate based on zeolite Y, defined by constant a of the unit cell of the crystal lattice, ranging from 24.4010-10 m to 24.1510-10 m, and based on aluminosilicate, containing silicon dioxide (SiO2) in amount exceeding 5 wt % and less than or equal to 95 wt %. The catalyst has the following characteristics: average pore diametre, total pore volume, BET specific surface area, volume of pores of different diametre, characterised by X-ray diffraction pattern and packing degree of the catalyst. ^ EFFECT: catalyst provides for suitable selectivity of middle distillates, ie fractions with initial boiling point of at least 150C and final boiling point which reaches initial boiling point of residue, for example below 340C or 370C. ^ 28 cl, 4 tbl, 21 ex |
