FIELD: oil-and-gas production. ^ SUBSTANCE: invention related to method of reforming catalysts activation and can be used in oil refining industry, oil-and-gas industry. Invention related to activation of reforming catalysts with a platinum content by treating it with circulating HBG under the high temperature, containing hydrocarbons C1-C3, in which inject HBG with a higher hydrogen concentration, increase of activation temperature started after reaching not greater than 1.5% vol. C2-C3 hydrocarbons concentration in HBG and humidity not greater than 30 mln -1, therefore continuously supply circulating with dried HBG with hydrogen concentration not less than 98% vol. in amounts 20-30 nm3 per 1 m3 of catalyst. The greatest effect of proposed method appears at activation temperature 500-520C and duration 24-48 hours, also using feeding HBG with C2-C3 hydrocarbons content not greater than 0.3% vol. ^ EFFECT: increase in interregenerative catalyst work cycle, reforming process temperature decrease, circulating HBG hydrogen concentration increase after catalyst activation. ^ 3 cl, 2 ex |
