Method for catalyst production for C5-C12 paraffins isomerization

A method of preparation of zirconia base catalyst for isomerization of hydrocarbons comprising:

• a) preparing a water suspension comprising zirconium hydroxide and a component of Group VI of the periodic table;
• b) adding to the suspension at least one compound of aluminum and/or silica;
• c) adding to the suspension a water solution of organic acid;
• d) adding to the suspension a water solution of cellulose ether;
• e) kneading the suspension to a moldable shaping mass;
• f) extruding the moldable shaping mass to form an extrudate;
• g) drying the extrudate at temperature range of 50-200° C.;
• h) calcining the extrudate in static atmosphere to form a support;
• i) peptizing the support with organic acid and a polymer;
• j) impregnating the support with a salt solution comprising at least one of the Pt, Pd, Sn, Re, or mixtures thereof to form an impregnated support;
• k) drying the impregnated support;
• l) calcining the impregnated support in air flow to produce an activated catalyst.
