Zirconium sulphate catalysts applied onto SiO2 and Al2O3 were prepared and investigated. Phase composition inherent in the catalysts, acidic properties according to the adsorption of CO and textural characteristics thereof were investigated. Catalytic activity level in the isomerization reaction of n–hexane was determined. It has been demonstrated that the most active catalytic system is presented by a catalyst based on Al2O3 carrier. The yield of hexane isomers wit the use of this catalyst amounts up to 75 mass % within the temperature range of 200–220 °C. It has been found that in the case of using alumina as a carrier the catalysts exhibit forming strong acid centers with the absorption bands of adsorbed CO being at 2210 and 2224 cm–1.
