The study considers the effect of iron and manganese introduction on the textural characteristics and phase composition of the alumina matrix used as a support for sulfated zirconia catalysts in hexane isomerization. The additives introduced during plasticization of aluminum hydroxide essentially enhance the catalytic activity, which is expressed in terms of hexane conversion, and the selectivity of isomerization toward the formation of hexane isomers. The distinctive feature of the doped catalysts is the formation of acid sites with LAS/BAS ≥ 2, which promote an increase in the yield of isomers and particularly the yield of high-octane 2,2-dimethylbutane.

The study considers the effect of fluorine doping of the alumina matrix used for the synthesis of supported sulfated zirconia catalysts. Hydrofluoric acid served as a fluorinating agent. The addition of fluorine was shown to affect the textural characteristics of the Al2O3 matrix and hence the surface area of sulfated zirconia catalysts based on the doped systems. It was found that the introduction of fluorine into the catalysts increases their activity (the conversion of hexane) and the yield of high-octane isomer 2,2-dimethylbutane.
