FIELD: chemistry.

SUBSTANCE: invention relates to Fischer-Tropsch synthesis catalysts. Described is a method of producing a precursor of a cobalt-containing Fischer-Tropsch synthesis catalyst, which involves adding a polyfunctional carboxylic acid of general formula HOOC-C*R₁C*R₂~COOH(1) where, C* in each of the groups C*R₁ and C*R₂ is a sp²-hybridised carbon atom and R₁ and R₂ are identical or different and each is selected from a group consisting of hydrogen and alkyl which contains not more than six carbon atoms, into and/or onto catalyst support particles, with the ratio of the amount of the polyfunctional carboxylic acid and the size of the surface of the support in the range of 0.3-10 mcmol of carboxylic acid/m² of the surface of the support; while adding carboxylic acid into and/or onto the catalyst support particles or after, simultaneously adding a cobalt compound into and/or onto the catalyst support particles and calcining the saturated support to form a precursor of a cobalt-containing Fischer-Tropsch synthesis catalyst.

EFFECT: described is a method of producing a Fischer-Tropsch synthesis catalyst which involves reduction of a catalyst precursor obtained using the described method; described is a method of producing hydrocarbons, which involves bringing into contact synthesis gas which contains hydrogen (H₂) and carbon monoxide (CO), at high temperature of 80°C-250°C and high pressure of 10-40 bar with a Fischer-Tropsch synthesis catalyst obtained using said method, and a Fischer-Tropsch reaction between hydrogen and carbon monoxide.
