FIELD: chemistry. ^ SUBSTANCE: invention relates to catalysed production in oil-refining and petrochemical industry and can be used to prepare a catalyst for isomerisation of light gasoline fractions. The invention describes a method of preparing an oxide catalyst for isomerisation of light gasoline fractions which contains a hydrogenating-dehydrogenating component and a support made through treatment in an alkaline medium of a mixture of hydroxides of zirconium, tungsten, aluminium, titanium and manganese at pH 9-11, temperature of 60-100C for 10-24 hours, washing with water in ratio of water: hydroxides equal to 100-300, filtration, drying the support at 100-150C for 10-20 hours and calcination in a current of dry air at 650-850C for 3-5 hours and then deposition of the hydrogenating-dehydrogenating component and thermal treatment of the catalyst. ^ EFFECT: higher specific surface area of the catalyst, total pore volume and activity during isomerisation of C7-C8 paraffin hydrocarbons. ^ 1 cl, 1 tbl, 12 ex |
