FIELD: material processing.
SUBSTANCE: highly active trimetallic material containing mixed transition metal oxide, a method for its preparation and a method for conversion have been developed. The material can be sulphidated to produce metal sulfides, which are used as a catalyst in the conversion method, for example, in hydrotreatment. Hydrotreatment may include hydrodenitrogenation, hydrodesulfurization, hydrodemetallization, hydrodesilication, hydro dearomatization, hydroisomerization, hydrotreatment, hydrogenation purification and hydrocracking. The catalyst preparation material contains a mixed transition metal oxide having the formula (MIa)m(MIIb)n(MIIIc)oOeq, where MI is a metal or a mixture of metals selected from group VIII (groups 8, 9 and 10 according to IUPAC); MII is a metal selected from group VIB (group 6 according to IUPAC); MIII is a metal selected from group VIB (group 6 according to IUPAC), which differs from MII; a, b, c and e represent the valence state of MI, MII, MIII and O; m, n, o and q represent the molar ratio of MI, MII, MIII and O, with m/(n+o) ranging from 1/10 to 10/1, where 0<n/o< 100 and 0<o/n<100, where q is greater than 0; and a, b, c, e, m, n, o, and q satisfy the equation: a × m + b × n + c × o + e × q = 0, and a mixed oxide of transition metals is further characterized by an X-ray diffractogram containing a broad peak between the values 2θ equal to 55° and 58°, with a full width at half maximum of more than 3° and at least one of the following: one or more sharp peaks between the values 2θ equal to 5° and 11.5°, with a full width at half maximum less than 0.3°; and one or more sharp peaks between the values of 2θ, equal to 11.5° and 32°, with a full width at half maximum less than 0.6°.
EFFECT: meeting the growing needs for conversion methods, including the need for catalysts with higher intrinsic activity per unit mass.
