FIELD: chemistry.
SUBSTANCE: method comprises producing a granular support containing alumina and 50-70 wt % of amorphous silica-alumina with a Si/Al mass ratio of 0.6 to 0.85, characterized by an X-ray diffraction pattern containing a wide peak in the range of 16.5-33.5° with a maximum of 23.1-23.4°, deposing the bimetallic complex compounds of Ni(NH4)x[HyW2O5(C6H5O7)2], where C6H5O7 - the partially deprotonated form of citric acid; x = 0.1 or 2; y = 2-x, drying the catalyst at the temperature of 100-250°C. The resulting catalyst contains, wt %: Ni(NH4)x[HyW2O5(C6H5O7)2] 32.6-39.6, amorphous aluminosilicate 30.2-47.2, γ-Al2O3 - the rest, which corresponds to the catalyst content calcined at 550°C, wt %: WO3 - 19.3-24.2, NiO 3.0-3.8, amorphous aluminosilicate 36.0-54.4; γ-Al2O3 the rest.
EFFECT: high yield of medium distillate fraction.
