FIELD: chemistry.
SUBSTANCE: invention relates to a method of cleaning hydrocarbon fractions from sulphur compounds and can be used in oil, gas, oil refining and chemical industries. The method is realised by treating compounds with an aqueous alkaline solution at temperature 5-90°C. The alkaline reagent used is a colloidal solution of aluminosilicate of formula: M2O·(0.1-1.2)Al2O3·(4-12)SiO2, where M denotes an alkali metal or ammonium cation with concentration 0.5-25 wt %.
EFFECT: cleaning hydrocarbon material from sulphur-containing compounds.
