FISCHER-TROPSCH CATALYST Russian patent published in 2007 - IPC B01J23/80 B01J37/03 B01J35/04 C07C1/04 

FIELD: disproportionation reaction catalysts.

SUBSTANCE: invention relates to Fischer-Tropsch catalyst containing cobalt and zinc, to a method for preparation thereof, and to Fischer-Tropsch process. Catalyst according to invention containing co-precipitated cobalt and zinc particles, which are characterized by volume-average size below 150 μm and particle size distribution wherein at least 90% of the catalyst particle volume is occupied by particles having size between 0.4 and 2.5 times that of the average particle size and wherein zinc/cobalt atomic ratio within a range of 40 to 0.1. Catalyst is prepared by introducing acid solution containing zinc and cobalt ions at summary concentration 0.1 to 5 mole/L and alkali solution to reactor containing aqueous medium wherein acid solution and alkali solution come into contact with each other in aqueous medium at pH 4-9 (deviating by at most 0.2 pH units) at stirring with a speed determined by supplied power between 1 and 300 kW/L aqueous medium and temperature from 15 to 75°C. Resulting cobalt and zinc-including precipitate separated from aqueous medium, dried, and further treated to produce desired catalyst. Employment of catalyst in Fischer-Tropsch process is likewise described.

EFFECT: enhanced strength and separation properties suitable for Fischer-Tropsch process.
