The invention relates to catalysts and methods for producing synthesis gas from organic feedstock and can be used for chemically processing a natural feed stock or synthetic organic products, for example lower hydrocarbons. Said invention makes it possible to develop an efficient catalyst and a method for catalytic conversion of said hydrocarbons. The inventive method for producing synthesis gas consists in interreacting gas-phase hydrocarbons with a mixture containing water and /or oxygen and carbon dioxide. The mixture can be diluted with nitrogen. Said method is carried out using catalysts comprising a phase which contains, at the same time, cations of silicium and nickel, at the nickel atomic ratio in relation to silicium ranging from 0.01 to 75. The proces for producing the synthesis gas from hydrocarbons can be also performed using the catalysts comprising a phase which, apart from the cations Ni<2+> and Si<4+>, contains the cations Al<3+>, at the nickel atomic ratio in relation to the sum of Al and Si ranging from 0.01 to 1.5, and at the aluminium atomic ratio in relation to Si ranging from 0.1 to 50. In addition, said phases can contain cations of alkali-earth metals and cations of alkali metals.
