COBALT CATALYST FOR SYNTHESIS OF C HYDROCARBONS, SYNTHESIS METHOD THEREOF AND METHOD OF PRODUCING SAID CATALYST Russian patent published in 2011 - IPC B01J21/04 B01J23/84 B01J27/12 B01J37/02 B01J37/08 C07C1/04 

FIELD: chemistry.

SUBSTANCE: invention relates to petrochemisry, gas chemistry, coal chemistry and a catalyst for synthesis of hydrocarbons containing 5 or more carbon atoms from CO and H₂ (Fischer-Tropsch synthesis), a method for synthesis of C₅₊ hydrocarbons using said catalyst and a method of producing said catalyst. Described is a catalyst for synthesis of C₅₊ hydrocarbons containing a support in form of fluorinated γ-aluminium oxide, 30 wt % cobalt and 0.5 wt % rhenium. Described is a method of producing said catalyst, involving preliminary thermal treatment of the γ-aluminium oxide-based support and then adding cobalt and rhenium via step-by-step saturation with aqueous solutions of cobalt nitrate and ammonium perrhenate and step-by-step thermal treatment, wherein the support used is fluorinated γ-aluminium oxide. The invention also describes a method of producing C₅₊ hydrocarbons via catalytic conversion of CO and H₂ using said catalyst.

EFFECT: high selectivity with respect to formation of desired hydrocarbon products (over 90%) and low selectivity with respect to formation of by-product - methane (less than 4%), wherein the relationship between the output of the desired products and the conversion of carbon oxide (output C₅₊-K_co) is linear in the conversion interval from 0 to 80-90%.
