Abstract

The effect of modification of bare sulfated zirconia catalyst by platinum, and rhenium loaded next to platinum in n-hexane isomerization has been shown. The promotion of unmodified sulfated zirconia by metallic components increases primary isomerization activity of catalyst. Besides, the impact of rhenium in bimetallic sulfated zirconia based catalyst is revealed. Moreover, it is established that impact of rhenium on platinum dispersion is favorable, but not enough for catalytic efficiency. Activity and/or selectivity of the mentioned mono- and bimetallic catalysts depend on favorable textural features, critical crystallite size, moderate acidity and finally on platinum dispersion..
