FIELD: chemistry.

SUBSTANCE: method of producing a Fischer-Tropsch synthesis catalyst, involving calcining material: nitrate, oxonitrate, hydroxide or oxohydroxide of aluminium, zirconium, silicon or titanium, at temperature of 400-800°C, grinding particles to size of not more than 0.5 mm, granulating, calcining the granules at temperature of 400-800°C, saturating with a solution of cobalt compounds in amount of 20-30 wt % and promoters selected from: Re, Ru, followed by calcination at temperature of 270-450°C, grinding the granules to particle size of not more than 0.5 mm, mixing with a zeolite selected from: ZSM-5, Y, β, content of which ranges from 30 to 70% of the mass of the ready catalyst, granulating the obtained mixture together with boehmite, the mass of which ranges from 10 to 20% of the mass of the mixture, and calcining at temperature of 400-600°C, ion exchange of the granules with soluble compounds of palladium or Fe, Co, Ni, with content thereof of 0.5-8.0% of the mass of the ready catalyst, in a suspension of granules and a solution of said metal compounds at temperature of 60-80°C for 1-3 hours, drying the suspension at temperature of 80-150°C and calcining the residue at temperature of 300-500°C, activating the catalyst with hydrogen at 250-500°C in a fixed bed Fischer-Tropsch synthesis reactor while passing hydrogen with volume rate of 3000 h^-1 at atmospheric pressure.

EFFECT: low cost of the catalyst, high stability of the catalyst.
