Abstract
The effect of iron and manganese additives on the textural characteristics and phase composition of the alumina matrix support was studied for sulfated zirconia catalysts of hexane isomerization. The additives introduced at the stage of plastification of aluminum hydroxide significantly improved the catalyst activity (hexane conversion and selectivity of isomerization to hexane isomers). A distinction of the modified catalysts is the formation of acid sites in a ratio of LAS : BAS ≥ 2, which increase the yield of isomers and especially of high-octane 2,2-dimethylbutane.
