FIELD: chemistry.
SUBSTANCE: invention relates to promoter catalysts on aluminosilicate carriers with defined content of macropores and to hydrocracking/hydroconversion and hydroprocessing methods which use these catalysts. A catalyst is described, which contains at least one hydro-dehydrogenating element chosen from a group consisting of elements of groups VIB and VIII of the periodic table of elements, 0.6 to 2.5% phosphorous. The said catalyst has total volume of pores of 0.35 to 0.74 ml/g, measured using mercury porosimetry and a non-zeolite carrier based on aluminosilicate, with the following characteristics: percentage content of silicon oxide 5 to 95 wt %; content of sodium less than 0.03%; total volume of pores, measured using mercury prosimetry, ranging from 0.45 to 0.96 ml/g; porosity, for which: i) volume of mesopores with diametre ranging from 40 to 150 Å and average pore diametre from 80 to140 Å ranges from 40 to 70% of the total volume of pores, measured using mercury porosimetry; ii) volume of macropores with diametre greater than 500 Å ranges from 30 to 60% of total volume of pores, measured using mercury porosimetry; BET specific surface area ranging from 100 to 550 m2/g; diffraction pattern in X-rays, which contains at least main characteristic bands of at least one of the transition modification aluminosilicates, which is part of a group which consists of alpha, rho, xi, eta, gamma, kappa, theta aluminosilicate modifications. Also described is a method of hydrocracking/hydroconverting hydrocarbon material, using a catalyst in one of the paragraphs described above. A method is also described for hydroprocessing hydrocarbon material, using a catalyst in accordance with one of the paragraphs described above.
EFFECT: design of a hydrocracking catalyst with high catalytic activity and selectivity.
