Bi (Pt-Sn and Pt-Re) and trimetallic (Pt-Sn-Re) catalysts supported on Al-HMS material (Si/Al = 10) were prepared and characterized by X-ray diffraction, N2 adsorption.desorption and temperature programmed reduction techniques. TPR results showed the interaction between metal species and mesoporous framework that can affect the acidity of mesoporous materials. Catalytic performance of samples was investigated for hydroconversion of n-heptane. A comparison of Pt-Re and Pt-Sn catalysts supported on Al-HMS-10 and Al2O3-Cl under the same conditions is made. Mesoporous catalysts exhibited better activity in comparison with Al2O3-Cl supported catalysts. Performance of trimetallic catalysts is better than bimetallic catalysts.
