CATALYSTS WITH HIGH COBALT CONTENT AND HIGH COBALT SURFACE AREA, PREPARATION AND APPLICATION THEREOF Russian patent published in 2009 - IPC B01J23/75 B01J21/04 B01J37/16 B01J37/03 

FIELD: chemistry.

SUBSTANCE: method of Fischer Tropsch synthesis of hydrocarbons includes the stage of carbon monoxide and hydrogen mixture interreaction in presence of catalyst in the form of particles containing homogenous mixture of cobalt and aluminium compounds at atomic ratio cobalt/aluminium in the range from 10:1 to 2:1 which after reducing at 425°C has cobalt surface area measured with hydrogen chemosorption at 150°C at least 30 m² per 1 g of catalyst. The catalyst preparation includes the stages: (i) of precipitation of unsoluble cobalt compound from water cobalt salt solution with excess of alkali precipitator; (ii) adding of soluble aluminium compound; (iii) aging of obtained precipitate in suspended form; (iv) extracting and drying of catalyst composition; (v) catalyst activation by its reducing with hydrogen-containing gas.

EFFECT: catalysts obtaining with high cobalt content and high cobalt surface area used for hydrogenating of unsaturated compounds in Fischer Tropsch synthesis.
