FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing carbon-based catalyst composition containing cobalt and molybdenum, as well as to a catalyst composition for converting synthesis gas in C2 and C3 alcohols. Above method involves dissolving a soluble cobalt-comprising compound and a soluble molybdenum-compound in organic solvents that are miscible with water to form a cobalt- and molybdenum-comprising solution; admixing an aqueous alkaline solution to the cobalt- and molybdenum-comprising solution in the presence of activated carbon support to form a solid catalyst precursor, separating the solid catalyst precursor from the liquids, washing and drying the solid catalyst precursor and calcining the solid catalyst precursor in an inert atmosphere. Relative molar ratio of elements in the catalyst composition is presented by formula: CoaMobC, where a is equal to 1·10-3-0.3, b is equal to 1·10-3-0.9.
EFFECT: obtained catalyst increases selectivity relative to alcohols and their output in comparison to common cobalt-molybdenum catalysts, and allows to reduce formation of such by-product as CO2.
