FIELD: chemistry.

SUBSTANCE: invention relates to a method of preparing a catalyst for Fischer-Tropsch synthesis, involving the following steps a)-d): a) pretreatment of aluminium oxide or silicon dioxide in spherical form through saturation in an aqueous solution with pH 7 or lower, which is selected from a group consisting of aqueous nitric acid solution, aqueous acetic acid solution, aqueous sulphuric acid solution, aqueous hydrochloric acid solution, ion-exchange water and distilled water; b) saturating the treated aluminium oxide or silicon dioxide in a zirconium solution whose volume is twice or more higher than the volume of aluminium oxide or silicon dioxide in order to deposit the treated aluminium oxide or silicon dioxide; c) annealing the aluminium oxide or silicon dioxide on which zirconium has been deposited to obtain a carrier in which zirconium in form of an oxide is selectively deposited near the outer surface of the metal carrier; d) depositing onto the carrier one or more types of metals selected from a group consisting of cobalt and ruthenium in amount ranging from 3 to 50 wt % in terms of the catalyst, where 75 wt % or more of the total amount of zirconium oxide is deposited on 1/5 or less portion of a radial area running from the outer surface of the catalyst to its centre. The invention also relates to a catalyst obtained using said method and a method of producing hydrocarbons via Fischer-Tropsch synthesis using said catalyst.

EFFECT: catalyst obtained using said method has improved catalyst performance.
