FIELD: chemistry.
SUBSTANCE: invention relates to a catalyst based on aluminophosphate zeolite APO-11 zeolite or silicoaluminophosphate SAPO-11 with a hierarchical pore structure. The finished catalyst contains, by wt %: 0.1-0.3 Pt, 0-0.2 Sn, 10.0-80.0 alumophosphate zeolite APO-11 or silicoaluminophosphate zeolite SAPO-11 with a hierarchical porous structure, Al2O3 - the rest.
EFFECT: decrease in the operating temperature range for the reactions of dehydrogenation of cyclic saturated hydrocarbons during the reforming of hydrotreated gasoline fractions, using a catalyst providing a relative residual C5+ content of naphthenic hydrocarbons in stabilized catalyst not more than 0,45 at temperatures not exceeding 480 degrees as compared with raw materials.
