Abstract:
The effect of the support nature on the hexane isomerization reaction parameters for SiO2- and Al2O3-supported sulfated zirconia catalysts with different textural characteristics has been studied. It has been shown that a higher hexane conversion is achieved in the presence of sulfated zirconia catalysts supported on aluminas. Using IR spectroscopy of adsorbed CO, it has been found that, in the Al2O3-supported catalysts, the concentration of Brønsted acid sites (BAS) characterized by adsorbed CO with an absorption band at 2170 cm–1 and strong Lewis acid sites (LAS) characterized by adsorbed CO with absorption bands at 2210 and 2224 cm–1 is higher than that in the SiO2-supported catalysts. In the Al2O3-supported catalysts with different textural characteristics, an increase in the contribution of LAS to the total acidity leads to a significant increase in the high-octane 2,2-dimethylbutane yield and the hexane isomerization depth.
