FIELD: chemistry.

SUBSTANCE: claimed are composite oxide for catalyst of reforming of hydrocarbons, method of catalyst obtaining and method of obtaining synthesis-gas in catalyst application. Composite oxide for catalyst of reforming of hydrocarbons, has composition described by the following formula (I) aM·bCo·cNi·dMg·eCa·fO (I), where a, b, c, d, e and f represent molar fractions, a+b+c+d+e=1, 0.0001<a≤0.20, 0<b≤0.20, 0<c≤0.20, 0.001<(b+c)≤0.20, 0.60<(d+e)≤0.9989, 0<d<0.9989, 0<e<0.9989, f represents number, necessary for preservation by elements of balance of charges with oxygen; and M represents, at least, one element from the number of elements from group 3B and elements from group 6A of periodic table, composite oxide being obtained by method which includes: obtaining mixed solution for impregnation, which contains catalytic active component in form of element Co or elements Co and Ni, one or several components, which improve anti-oxidation resistance, selected from group, consisting of group 3B elements and elements of 6A group of periodic table, and one or several additional metal components, selected from group, consisting of Ca and Mg; impregnation of carrier, obtained from porous formed body, selected from magnesium oxide or composite, formed from magnesium oxide and calcium oxide, mixed with solution for impregnation; drying of carrier, impregnated with mixed solution for impregnation; and calcinations of dried carrier in oxidative atmosphere.

EFFECT: catalyst preserves catalytic activity at high level for long time period, is characterised by low amount of carbon, precipitated on catalyst surface in synthesis-gas obtaining.
