FIELD: fuel production. SUBSTANCE: kerosene fraction with boiling range 120(140)-225(245) C and diesel fraction with boiling range 150(220)-340(370) are separately subjected to hydrotreatment. Treated diesel fraction is then rectified to produce 50(100)-150(280) fraction which is combined with crude kerosene fraction hydrotreatment product at weight ratio from 1:99 to 30:70. Kerosene fraction has been treated at 240-330 C, pressure 2.5-3.5 MPa, volume velocity of raw material 5-15 h-1 with 150-400 cu.nm of hydrogen-containing gas per 1 cu.m of raw material. EFFECT: improved performance characteristics of fuel. 3 cl
