Determination of Activity and Selectivity of Catalytic Reforming of N–Heptane by Pt–Ir Supported on Gamma–Alumina

Mehdi Vadi, Davood Wadi

Abstract :

Bimetallic catalyst platinum–iridium supported by Gamma–alumina was prepared by impregnation with solution containing compounds of H2PtCl6 and IrBr3. The Platinum concentration was kept constant at 0.3wt% while the concentration of the iridium was 0.3wt%. The activity and selectivity of catalyst were determined under conditions at 450–500 ºC and 15–30 atm. Molar ratio H2/C7H6=5 and VVH=1.5mL/h for converted n–heptane. The results showed that when Ir is present, the catalyst is stable and have much higher selectivity for isomerization reaction. It was shown that Ir modifies the acidity of support, resulting to higher selectivity for isomerization, and modifies the properties of the Pt.
