FIELD: gasoline production. SUBSTANCE: in a process of catalytic reforming of gasoline fractions, circulating hydrogen-containing gas is purified from hydrogen sulfide on nickel-chromium catalyst, which has been preliminarily treated at 140-230 C with a hydrogen- containing gas comprising 12 vol. % of C2-C7-hydrocarbons, 20- 1200 vol. ppm of steam, and 1-80 vol. ppm of hydrogen sulfide. EFFECT: enhanced efficiency. 1 tbl
