FIELD: purification of sulfur-containing raw materials with sulfur content up to 6 mass %. SUBSTANCE: hydrocarbon raw materials are mixed at 1-100 C with chemisorbent (diameter of its grains being 3-10 mm) at their ratio 1-20: 1. Thus obtained mixture is allowed to stand within 10 min - 8 h. Then sulfur-free hydrocarbon raw materials are extracted by benzine, or by n-pentane, or by isopentane, and extragent being distilled. Said chemisorbent comprises metal of VI or VIII group of Periodic Table or metal of group of ferrum, or copper, or cadmium, or titanium, or vanadium or their derivatives being applied on carrier of fireproof porous material (e.g. aluminium oxide, activated coal, polymer). EFFECT: improves efficiency of the method. |
