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 24.40·10-10 m to 24.15·10-10 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 150°C and final boiling point which reaches initial boiling point of residue, for example below 340°C or 370°C.
