FIELD: petroleum processing. SUBSTANCE: sulfur compounds are oxidized when raw material is brought into contact with working reagent containing transition metal ions in oxidation state superior to their lowest oxidation state. Resulting mixture is then separated into purified hydrocarbon material and exhausted working reagent. The latter, according to invention, additionally contains ions of at least one metal or metal itself selected from metametal group including copper, lead, tin, and gold. EFFECT: increased degree of removal of sulfur compounds. 2 cl, 4 tbl, 5 ex
