FIELD: oil and gas production. ^ SUBSTANCE: invention can be used in oil refining, petrochemical and gas industry. The invention concerns the method for production of high-grade petrol that involves preliminary hydrofining of straight-run petrol, fractionation of a hydrogenation product with recovering of light boiling, medium boiling and heavy boiling fractions, isomerisation of the light boiling fraction with recovering of an isomerizate, catalytic reforming of the heavy boiling fraction with rectification recovering of a reformate fraction, boiling away within the temperature range "Ü"-85C and the catalytic reforming petrol, the medium boiling fraction which boils away within the temperature range 70 to 85C, together with the reformate fraction "Ü"-85C is hydroisomerised at temperature 260-290C with a platinum-aluminium-mordenite catalyst with recoverying of the hydroisomerisate and mixing the catalytic reforming petrol, the isomerisate and hydroisomerisate to prepare an end product. ^ EFFECT: improved ecological characteristics of high-grade petrol and increased development of the end product. ^ 2 cl, 3 ex, 2 tbl |
