FIELD: oil industry.

SUBSTANCE: invention relates to production of catalysts for hydrocracking and hydrofining of heavy oil residues, viscous and high viscous oil. Disclosed catalyst contains highly porous cellular carrier made of metal: nickel, chromium, copper, iron, titanium, aluminum in individual form or in combinations with each other, or from aluminum oxide, or iron oxide, or in combination with each other, active component selected from: nickel, chromium, copper, iron, titanium, aluminum, aluminum oxide, iron oxide with porosity of at least 85 %, average pore size (cells) of 0.5–6.0 mm, on high-porous cellular support is fixed layer of a secondary carrier selected from: zeolite, aluminum oxide, iron oxide, silicon oxide, titanium oxide, zirconium oxide, aluminosilicate, iron silicate, clay or any combination thereof, secondary carrier is characterized by thickness from 10 to 2,000 mcm, specific surface area of not less than 20 m²/g, pore volume from 0.1 to 1.0 cm³/g, in which pores with diameter greater than 5 nm make not less than 50 % of total pore volume, presence of Bronsted acid and Lewis acid centers, wherein according to temperature-programmed desorption of ammonia, the number of medium and strong acid centers of Bronsted and Lewis with temperature ranges of ammonia desorption of 250–350 °C and more than 350 °C is 1–1,500 and 1–1,500 mcmol/g respectively, and ratio of medium and strong acid centers of Bronsted and Lewis is 1–10:1–5, secondary carrier in total catalyst composition is not less than 5 wt %, active component is fixed on a secondary carrier in the following ratio of components, wt %: secondary carrier 5.0–40.0, active component 0.05–40.0, modifying element 0–40.0, highly porous cellular material – the rest.

EFFECT: technical result consists in increase in catalyst activity, duration of its inter-regeneration period of operation and improvement of mass exchange, high efficiency of hydrocracking and hydrofining.
