METHOD FOR HYDROCRACKING CATALYST COMPOSITIONS PRODUCTION Russian patent published in 2017 - IPC B01J21/04 B01J29/14 B01J37/02 C10G47/20 C10G45/20 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for obtaining of hydrocracking catalyst selective in terms of naphtha, containing 3 to 4.8% of molybdenum in terms of metal and 1.5 to 3% of nickel in terms of metal, which includes introduction into a refractory oxide medium containing an aluminium oxide binder and a Y zeolite component in an amount of 65 to 75 % per the total weight of catalyst, nickel and molybdenum in solution containing citric acid, where the Y zeolite component size is equal to an elementary cell in the range from 24.42 to 24.52 E, molar ratio of silicon dioxide and aluminium oxide (SD/AO) ranges from 10 to 15 and the surface area varies from 910 to 1020 m²/g. The invention also refers to the hydrocarbons hydrocracking technique, which includes raw material contact with a catalyst composition prepared by the method stated above at an elevated temperature.

EFFECT: obtaining of a hydrocracking catalyst selective against naphtha.
