FIELD: chemistry.

SUBSTANCE: invention relates to methods of reducing platinum-rhenium reforming catalyst and can be used on oil-refining, petrochemical and gas production enterprises. A method is proposed for reducing platinum-rhenium reforming catalyst through high temperature treatment with a circulating reforming hydrogen-containing gas, containing an additive of sulphur compounds in amount of 0.05-0.30 % of the mass of catalyst (in terms of sulphur) in two stages. The method is distinguished by that, the platinum-rhenium catalyst is pre-treated only with hydrogen-containing gas at temperature 480-500°C for 2-4 hours, and treatment with sulphur compound additives at the first stage is done at temperature 480-400°C, and 280-260°C at the second stage.

EFFECT: significant increase of octane number of reformate, as well as inter-regeneration cycle of the catalyst.
