CATALYST OF ISOMERIZATION OF LIGHT PETROL FRACTIONS AND METHOD OF ITS PRODUCTION Russian patent published in 2017 - IPC C07C5/27 C07C9/16 B01J37/02 B01J21/04 B01J21/06 B01J23/62 

FIELD: chemistry.

SUBSTANCE: method includes preparing a support, shaping, drying, calcining, and impregnating it with a solution of zirconium sulfate, followed by drying and calcination, and then treating with a hexachloroplatinic acid solution, drying and calcining. The support is obtained by treatment of aluminium hydroxide with a pseudo-bimitic structure produced by reprecipitation of aluminium hydroxide by a nitrate method in a continuous precipitation mode, a solution of tin sulfate, followed by drying to a moisture content of 58-60 wt %, by moulding into granules with a diameter of 1.5-1.7 mm, drying to a moisture content of not more than 20 wt % and calcining to a moisture content of not more than 3 wt %, and impregnation with a hexachloroplatinic acid solution is carried out with the addition of sulfuric acid. A catalyst for isomerization of light gasoline fractions, which is obtained by the process of the invention, is also claimed and which contains components in wt %: Pt - 0.1-0.3, ZrO₂ - 20-30, S0₄^2- - 6-10, Sn - 0.15-0.50, Al₂O₃ is the rest.

EFFECT: high yield, maintaining a low content of active components in the catalyst.
