FIELD: chemistry.

SUBSTANCE: catalyst for reforming gasoline fractions containing platinum, rhenium, chlorine, and a carrier is described, the catalyst comprising a surface compound of dehydrated zirconyl aluminium oxodifluoride of general formula Al₂O₃[ZrOF₂]_x as a support with the weight stoichiometric coefficients x from 1.0·10^-2 up to 10.0·10^-2 at the following content of the components, wt %: platinum 0.1-0.5, rhenium 0.1-0.4, chlorine 0.7-1.3, carrier - the rest. The method of producing a catalyst for reforming gasoline fractions comprises preparing the support by mixing an aluminium hydroxide of a pseudoboehmite structure with an aqueous solution of hexafluorozirconic acid H₂ZrF₆, containing organic components (formic, acetic, oxalic, citric acid, or their mixture with a total acid modulus of, at least, 0.01 g-mol acid/g-mole of Al₂O₃) followed by drying to a moisture content of 58-65 wt %, by moulding into extrudates with a diameter of 1.0-3.0 mm, drying to a moisture content of not more than 20 wt % and calcining to a moisture content of not more than 3 wt %.

EFFECT: production of reformed gasolines with reduced aromatic hydrocarbon content while maintaining the octane number, increasing the yield.
