FIELD: crude oil treatment and petroleum processing. SUBSTANCE: isolation of organosulfur compounds from kerosene and diesel fraction is effected by adsorption in centrifugal field by common rotation of pure adsorbent and initial oil stock in rotor for 30-40 min, amounts of adsorbent and oil stock being at ratio (1.5-2.0):1 and rotor speed being within a range of 2000-2500 rpm. Method allows operations of modifying and impregnating adsorbents to be avoided, short-supply and environmentally dangerous reagents are unnecessary, consumption of adsorbent is 6-10-fold lower, and degree of removal of impurities is raised by 2.5-3 times. EFFECT: enhanced process efficiency. 1 dwg, 2 tbl, 8 ex
