Enhanced activity and selectivity in n-octane isomerization using a bifunctional SCILL catalyst

► A bifunctional SCILL (“Solid Catalyst with Ionic Liquid Layer”) system with acidic and hydrogenation functions is presented. ► High activity and selectivity in n-octane skeleton isomerization have been shown. ► Activity and selectivity of the SCILL catalyst increase with increasing H2-pressure. ► Cooperative interaction of Pt, acidic ionic liquid, and hydrogen is demonstrated. ► The catalyst system shows remarkable activity at 120 °C and 40 bar hydrogen pressure.
