FIELD: chemistry.SUBSTANCE: invention relates to a mixed transition metal oxide and its use as a catalyst or precursor to a catalyst, such as a catalyst or precursor to a catalyst for the conversion of hydrocarbons or, more specifically, a catalyst or precursor to a hydro-treatment catalyst. The catalyst material is a mixed transition metal oxide having the formula: (MIa)m(MIIb)n(MIIIc)o(MIVd)pOeq, where MIis a metal or a mixture of metals selected from Group IB (IUPAC Group 11), Group IIB (IUPAC Group 12), Group VIIB (IUPAC Group 7), Group IIIA (IUPAC Group 13), Group IVA (IUPAC Group 14) and Group IVB (Group 4 IUPAC); MIIis a metal or a mixture of metals selected from Group VIII (IUPAC Groups 8, 9, and 10); MIIIis a metal selected from Group VIB (IUPAC Group 6); MIVis a metal selected from Group VIB (IUPAC Group 6), which is different from MIII.EFFECT: catalyst with a higher intrinsic activity per unit mass is obtained.24 cl, 8 tbl, 8 ex, 2 dwg |
