FIELD: chemistry.

SUBSTANCE: present invention relates to a sulphur-resistant, noble metal-containing catalyst for hydrogenating aromatic compounds, a method of producing said catalyst and a method of hydrogenating aromatic compounds. Described is a method of preparing a catalyst composition for hydrogenating aromatic compounds which is resistant to the poisonous effect of sulphur, having surface area ranging from 300 m²/g to 600 m²/g, where the said method involves: combined grinding of a zirconium compound and an inorganic oxide selected from a group comprising silicon dioxide, aluminium oxide and silicon dioxide-aluminium oxide to form a mixture; forming a particle agglomarate containing said mixture; calcining said particle agglomerate to obtained calcined particles suitable for use as a catalyst support; and adding a noble metal to said catalyst support, said noble metal being selected from a group comprising platinum, palladium and combination thereof, to obtain an intermediate catalyst composition. Described is a catalyst for hydrogenating aromatic compounds with surface area ranging from 300 m²/g to 600 m²/g, which is resistant to the poisonous effect of sulphur and containing: a noble metal selected from a group comprising platinum, palladium and combination thereof, and a calcined mixture as the catalyst support, in which before calcination, said mixture contains a zirconium compound and an inorganic compound selected from a group comprising silicon dioxide, aluminium oxide, silicon dioxide-aluminium oxide, and in which said noble metal is present in the said catalyst for hydrogenating aromatic compounds in amount ranging from 0.01 wt % to 5 wt %, wherein the wt % is taken relative to the elementary metal, and in which said catalyst for hydrogenating aromatic compounds contains 1-30 wt % zirconium dioxide and 60-99 wt % said inorganic oxide. Described is a method of hydrogenating aromatic compounds of hydrocarbon material containing sulphur compounds using the described catalyst. Described is a composition for hydrogenating aromatic compounds obtained using the method described above.

EFFECT: high resistance of the catalyst to the poisonous effect of sulphur and higher activity when hydrogenating aromatic compounds.
