FIELD: process engineering.
SUBSTANCE: invention relates to activation of catalysts for diesel fuel hydrofining and can be used in oil processing and petrochemical industries. Activation of nickel-molybdenum-alumina catalysts comprises bringing the catalyst in contact with the solution of ferriphenyl siloxane in organic solvent at cavitation hydrodynamic processing in bubble-cavitation layer of inert gas inside cavitation flow reactor at oscillation intensity of 0.25-0.55 W/m2 and 15-45°C for 5-25 min. Then, catalyst is cured in organic solvent at a room temperature, solvent is stripped and catalyst if dried and heat-treated.
EFFECT: higher desulfurising activity.
