The Effect of the Addition of Re and Ge on the Properties of Pt/Al2O3

Abstract

The effect of Re and Ge addition to Pt/Al2O3 was studied. Mono-, bi- and a trimetallic catalysts were prepared and characterized by TPR, XPS, TPO and by the n-pentane, cyclohexane (CH) and n-octane reactions. It was found that the trimetallic was the most active and stable catalyst and showed selectivities to aromatics and isomers very similar to the bimetallic germanium-based catalyst.
