Abstract

The effect of the support nature on the performance of hexane isomerization reaction was studied for the sulfated zirconiа catalysts supported on SiO2 and Al2O3, which have different textural characteristics. It was shown that a higher conversion of hexane is reached over sulfated zirconiа catalysts supported on aluminum oxides. IR spectroscopy of adsorbed CO revealed that the concentration of Broensted acid sites (BAS), which are characterized by adsorbed CO with the absorption band (a.b.) at 2170 cm–1, and strong Lewis acid sites (LAS), which are characterized by adsorbed CO with a.b. at 2210 and 2224 cm–1, is higher in the Al2O3-supported catalysts compared to the SiO2-supported ones. In the Al2O3-supported catalysts with different textural characteristics, an increase in the contribution of LAS to the total acidity essentially increases the yield of high-octane 2,2-dimethylbutane and the depth of hexane isomerization.
