METHOD OF PREPARING OXIDE CATALYST FOR ISOMERISATION OF LIGHT GASOLINE FRACTIONS Russian patent published in 2010 - IPC B01J21/02 B01J23/64 B01J21/06 B01J37/02 C07C5/27 

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 60-100°C for 10-24 hours, washing with water in ratio of water: hydroxides equal to 100-300, filtration, drying the support at 100-150°C for 10-20 hours and calcination in a current of dry air at 650-850°C 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.
