FIELD: methods of preparation of catalysts for reforming of gasoline fractions in oil producing and petrochemical industries for production of high-octane motor fuels, aromatic hydrocarbons and commercial hydrogen.
SUBSTANCE: proposed method includes vacuum treatment of carrier, recirculation through aqueous solution of hydrochloric and acetic acids under vacuum, recirculation of impregnating solution; solutions of chloro-platinous and rhenium acids are introduced into impregnating solution at constant rate, after which solution is subjected to drying and calcination; treatment of carrier with impregnating solution is carried out at three stages: at first and second stages, temperature of circulating impregnating solution does not exceed 30°C and at third stage its temperature is not below 70°C.
EFFECT: enhanced activity, selectivity and stability of catalyst; reduced usage of metals; reduction of wastes and losses of platinum and rhenium.
