FIELD: chemistry.SUBSTANCE: described is composition of catalyst of aromatic hydrocarbon hydration or composition for obtaining catalyst of aromatic hydrocarbon hydration, where composition contains more than 51% of pores, which have diameter more than 350 ? (35 nm), counting from their total volume, which includes amorphous silicon oxide-aluminium oxide, in which percentage of pores with diameter more than 5000 ? (500 nm) counting from total volume of pores, constitutes less than 4%. Described is method of aromatic hydrocarbons hydration in hydrocarbon raw material, containing aromatic hydrocarbons in concentration from 1% wt to 80% wt, and said method includes: contact of said hydrocarbon raw material at pressure between 10 and 100 bars and temperature from 125°C to 350°C with said composition; and obtaining product, which has reduced concentration of aromatic hydrocarbons. Described is method of obtaining catalyst of hydrating hydrocarbons mentioned above, which includes obtaining carrier composition by agglomeration of mixture, which includes water and amorphous silicon oxide-aluminium oxide, and drying obtained agglomerate; and introduction of carrier of noble metal, selected from group consisting of platinum, palladium and their combination, into said carrier composition with obtaining impregnated carrier composition.EFFECT: increased catalytic activity.14 cl, 2 tbl, 2 ex |
