FIELD: petrochemical process catalyst. ^ SUBSTANCE: invention relates to a method of preparing catalyst for use in Fischer-Tropsch process and to catalyst obtained according present invention. Preparation of catalyst suitable for conversion at least one synthesis gas component comprises: providing aqueous solution of organic acid; adding iron metal to acid solution; passing oxidant through the solution until iron metal is consumed and iron-containing slurry formed; grinding resulting slurry to achieve average particle size less than about 2 mum; adding at least one promoter to ground iron-containing slurry to form product suspension, concentration of said promoter being such as to obtain said product suspension containing solid phase constituting from about 10 to about 40% of the weight of suspension, including said promoter; performing spray drying of suspension to obtain particles; and calcining these particles to obtain desired catalyst. ^ EFFECT: optimized catalyst preparation procedure. ^ 23 cl, 2 dwg, 1 tbl, 12 ex |
