METHOD OF PRODUCING A CATALYST FOR DEMETALLISATION OF OIL FRACTIONS Russian patent published in 2019 - IPC B01J32/00 B01J35/04 B01J21/04 B01J37/02 B01J23/88 C10G45/08 C10G45/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil refining industry, in particular, to catalysts for hydro-regeneration of oil fractions. Disclosed is a method of producing a catalyst for demetallisation of petroleum fractions by preliminary preparation of a catalyst support by depositing aluminum hydroxide from a solution of aluminum nitrate or aluminum alkoxide in the presence of an aqueous dispersion of macropore template with particle diameter of 0.1–2.0 mcm in amount of 10–35 wt%. on dry catalyst support, adding zeolite in amount of 5–30 wt% to the obtained mass of the powder. on a dry catalyst support, by molding, drying and calcining, and then applying the active components onto the prepared carrier, by impregnating with a solution of nickel, cobalt and molybdenum precursors. Macropore template is represented by a paraffin emulsion or a dispersion of the styrene-acrylic copolymer. Zeolite used is ultra stable zeolite Y and/or high-silica zeolite ZSM-5. Content of active components in terms of oxides in calcined catalyst is 5.0–7.0 wt%. MoO₃; 0.5–0.7 wt% CoO; 0.7–1.1 wt% NiO. Produced catalyst has specific surface area of not less than 180 m²/g with specific pore volume of not less than 0.25 cm³/g.

EFFECT: disclosed method of producing a demethallisation catalyst, having adsorption and catalysis functions, provides, in conditions of hydrogenation refining of oil fractions, a removal depth of both nickel and vanadium of 85 % and more.
