CATALYST FOR FISCHER-TROPSCH PROCESS IN COMPACT VERSION AND PRODUCTION METHOD THEREOF (VERSIONS) Russian patent published in 2017 - IPC B01J23/75 B01J37/02 B01J37/03 C01C1/04 

FIELD: chemistry.

SUBSTANCE: invention relates to petrochemistry, gas chemistry, coal chemistry and concerns Fischer-Tropsch synthesis in a compact version, which requires synthesis of hydrocarbons in high-efficiency modes at a rate of more than 1,000 kg/m³_cat⋅h. Catalyst is characterised by that it has specific surface area in tempered state of 50–92 m²/g and after recovery specific surface area of metal cobalt 10.3–25.5 m²/g, average size of particles of metal cobalt 5.0–18.5 nm and particle dispersity 5.4–20.0 % and containing 41–50 wt% of cobalt from weight of calcined catalyst and a support with specific surface area 86–423 m²/g and pore volume of support of 0.20–1.07 cm³/g, selected from: zirconium oxide or aluminium oxide, modified by applying zirconium oxide, or silicon oxide, modified by applying zirconium oxide, or zirconium oxide, modified by depositing aluminium oxide, or silicon oxide modified by application of aluminium oxide, wherein amount of modifying is oxide is 10–40 wt% of weight of support. Method of producing catalyst according to first version comprises multiple impregnation of support with aqueous solution of cobalt precursor with subsequent drying and calcining, or co-precipitation of cobalt carbonate from basic solution in presence of support, drying and calcination – according to second version.

EFFECT: higher selectivity of catalyst with respect to formation of hydrocarbons C₅₊ of not less than 60 % with CO conversion of not less than 70 % and maximum output of catalyst for high-molecular hydrocarbons is not less than 1,000 kg/m³_cat⋅h.
