FIELD: chemistry.
SUBSTANCE: invention relates to a method of removing contaminant sulphur compounds, particularly thiophene sulphur compounds, from hydrocarbon material, which involves bringing the material into contact with a sulphided nickel adsorbent in the presence of hydrogen, where part of the nickel is present in metallic form, for which the kinetic constant during hydrogenation of tetraline at 150°C is less than 0.01 l/s.g of catalyst, in which a) the nickel adsorbent additionally contains a metal oxide, which forms stable sulphides in conditions used in the process of removing contaminant sulphur compounds from hydrocarbon material, or b) in which the said hydrocarbon material is treated by a metal oxide, which forms stable sulphides in the process of removing contaminant sulphur compounds from hydrocarbon material after bringing into contact with said sulphided nickel adsorbent.
EFFECT: increased capacity of adsorbent to a value, comparable for sulphides and mercaptans.
