METHOD FOR PRODUCING HYDROCRACKING CATALYST Russian patent published in 2018 - IPC B01J37/02 B01J37/04 B01J29/16 C10G47/20 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the process for preparation of hydrocracking catalyst which comprises the stages: (a) mixing zeolite Y having a unit cell size in the range from 24.42 to 24.52 E, the molar ratio of silica to alumina (SAR) in the range from 10 to 15 and surface area in the range from 910 to 1020 m², with binder based on aluminium oxide and two or more catalytically active metal-containing components, wherein said metal-containing components are contained in one or more solutions, wherein the zeolite Y is present in amount of 40 wt % or more based on the total weight of zeolite Y and aluminium binder; (b) extruding the mixture obtained in stage (a); drying the extruded mixture obtained at the stage; (d) calcination of dried and extruded mixture obtained at the stage(c); and (e) mixing the calcined product obtained in the stage (d) with two or more catalytically active metal-containing components, where said metal-containing components are contained in one or more solutions. The invention further provides hydrocracking method for hydrocarbon-containing feedstock, wherein the process comprises introducing feedstock at elevated temperature into contact with hydrocracking catalyst produced by the present process.

EFFECT: higher activity and selectivity of the resulting catalyst.
