FIELD: gas fuel production and catalysts. SUBSTANCE: catalyst represents a lamellar hydrosilicate phase with stivensite-type structure of general formula (NixMe1-x)3Si4O10(OH)2.nH2O, wherein Me denotes one or several alkali-earth metals, x varies between 0.01 and 1, and n is less than 50, or metasilicate phase with enstatite-type structure of general formula (NixMe1-x)3SiO3, wherein Me, x, and n are as above, or hydroaluminosilicate phase with amesite-type structure of general formula (Ni1-x-yMexAly)3(Al3ySi2-3yO5)(OH)4.nH2O, wherein Me denotes one or several alkali-earth metals, x is below 0.8, y varies between 0.02 and 0.64, and n is less than 50, or hydroaluminosilicate phase with chlorite-type structure of general formula (Ni1-x-yMexAly)3(Al3ySi2-3yO5)(OH)4.nH2O,, wherein Me denotes one or several alkali-earth metals, x is below 0.8, y varies between 0.02 and 0.62, and n is less than 50, nickel-to-silicon atomic ratio ranging from 0.01 to 75. Production of synthesis gas from hydrocarbons is effected by bringing hydrocarbons into gas-phase interaction with an optionally nitrogen-diluted mixture of water and/or oxygen, and carbon dioxide in presence of above-indicated catalysts. Absence of silica phase in catalyst composition ensures process stability. EFFECT: increased activity and selectivity of catalyst. 6 cl, 1 tbl, 7 ex |
