    The invention relates to catalytic chemistry, in particular a catalyst (QD) having specific shape particles that are used to convert hydrocarbons. An increase in the activity of CT is achieved by a new geometric shape. The structure of QDs includes: NiO and / or CoO, Mo.0, in combination with AljO, containing SiOj. CT consists of extruded particles, the cross sections of which are formed from figures that have widely-bending arcs as the outer border and are interconnected by short arcs of opposed bending, with straight lines between any two points located on the wide-bending arc outside the geometric body. The particles have a diameter of 0.5–3.0 mm, a pore volume of 0.4–0.9, an average pore diameter of 4–20 nm, a specific surface area of 150–300, a ratio of a geometric surface and a geometric volume of 100–600 cm, and a fraction of pores with a diameter 25 - 3750 nm less than 5% of the total pore volume and the proportion of pores with a diameter of 3 - 10 nm not less than 90% of the total pore volume. The particles of CT are a vertebrate formation with three arms. Mostly CT contains in its composition, wt.%: 2-5 NiO and / or CoO; 8-15 MOJO; 0.3-3.0 SiO and the rest The CT test shows that it provides a better degree of desulfurization than the known (in the form of a three-pointed star). 5 hp f-ly, 2 ill., 2 tab.

    To improve the plasticity and formability of the mass, an additional 0.5% by weight of nitric acid (in terms of dried alumina) is added and stirred until the mass becomes extrudable. Then it is molded with a screw press. At the same time, dies with a profile of a clover leaf (A), a three-pointed star (B) and with a three-sleeve vertebral profile (C) are used as dies.
