PROCESS OF PRODUCTION OF HYDROCARBONS FROM CARBON OXIDES AND HYDROGEN Russian patent published in 2003 - IPC

FIELD: petrochemical processes. SUBSTANCE: synthesis gas is brought into contact with catalytic composition consisting of mixture composed of (i) iron-containing Fischer-Tropsch synthesis catalyst in oxidized or reduced form promoted by aluminum, silicon, magnesium, potassium, and calcium oxides, and (ii) acid component: crystalline aluminosilicate or silicoaluminophosphate. Process employs circulation of gas flow after reaction with volume ratio of amount of circulating gas to amount of initial synthesis gas is equal to 1-1000. Process is carried out at 220-400 C, pressure 10-100 atm, synthesis gas volume flow rate 100-5000 h^-1, molar ratio H₂/CO in initial synthesis gas 1-3, and volume content of CO₂ in gas flow at the inlet of reactor between 0.01 and 40%. EFFECT: increased selectivity and productivity of catalyst regarding liquid hydrocarbons. 7 cl, 1 tbl, 16 ex
