FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing synthetic aviation fuel from hydrocarbons obtained via Fischer-Tropsch method, involving separation from the synthesised liquid products of the 135-280°C fraction which is subsequently divided into two fractions 135-190°C and 190-280°C by rectification, after which the fraction with the lowest boiling point is subjected to aromatisation at temperature of 400-500°C, at hydrogen pressure of 1.8-2.5 MPa, with volume rate of feeding material of 1.5-2.0 h^-1 and ratio of hydrogen to the material of 1100-1500:1 nl/l over an aluminium-platinum catalyst promoted with rhenium, which contains 0.28-0.32 wt % platinum and 0.28-0.52 wt % rhenium, applied on a γ-Al₂O₃ support, content of foreign-metal impurities of which is not more than 1500 ppm, and the fraction with the highest boiling point is successively subjected to hydroisomerisation at temperature of 200-400°C, at hydrogen pressure of 2.0-7.0 MPa, volume rate of feeding material of 0.2-2.5 h^-1, at ratio of hydrogen to the material of 300-1500:1 nl/l over a catalyst containing a catalytically active component - platinum, which is applied on a zeolite-containing support and a binder, wherein content of platinum in the catalyst is in the range of 0.15-0.60 wt %, content of zeolite is equal to 5-60 wt %, which is selected from the group: ZSM-5, ZSM-23, p, SAPO-11 or SAPO-41, wherein the binder used is γ-Al₂O₃ in the remaining amount, and then subjected to hydrofinishing at temperature of 180-240°C, at hydrogen pressure of 2.0-4.0 MPa, volume rate of feeding material of 1.0-12.0 h^-1, with ratio of hydrogen to the material of 300-500:1 nl/l over an aluminium-palladium catalyst containing 0.2-2.0 wt % palladium, on γ-aluminium oxide with average pore radius of 4.0-10.0 nm, content of foreign-metal impurities of which is not more than 1500 ppm, after which the fractions are mixed and stabilised.

EFFECT: high output of end products which are suitable for producing high-quality aviation fuel after mixing and stabilisation.
