METHOD OF PREPARING Ni-W CATALYST FOR HYDROCRACKING HYDROCARBON MATERIAL

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a method for preparing a catalyst for hydrocracking a hydrocarbon material by impregnating a calcined amorphous silica-alumina carrier with an aqueous solution obtained by mixing at a temperature of 90–95 °C in an aqueous solution of orthophosphoric acid 45–75 g/l, tungsten (III) oxide 290–460 g/l and nickel (II) carbonate 65–120 g/l, which is stabilized by a mixture of citric and oxalic acids with a concentration of 28–65 g/l with the formation of a stable water complex of active components, followed by drying the catalyst at 120–150 °C and further sulphidizing.;EFFECT: technical result consists in preparing a catalyst for the hydrocracking of hydrocarbon material with high activity and simplifying the process for its preparation.;4 cl, 3 tbl, 7 ex
