FIELD: isomerization catalysts. SUBSTANCE: catalyst contains 65-79% of crystalline aluminosilicate of the pentasil type with silica-to- alumina molar ratio 25 to 100 and residual content of sodium ions equivalent to 0.05-0.1% sodium oxide, 0.5-3.0% of zinc oxide, 0.1-5.0% of rare-earth metal oxides, 0.05-2.5% of cobalt oxide, and binder - the balance. Another version of invention recommends, wt %: zinc oxide 0.5-3.0, rare-earth metal oxides 0.1-5.0, copper chromite 0.1-0.3, above defined aluminosilicate 65-70, and binder. EFFECT: increased catalytic activity. 4 cl, 3 tbl, 23 ex
