Abstract
The excellent performance of the Pt/Re/CeZrO4 catalyst, for the CO Water Gas Shift reaction, is presented. A preliminary comparative study, on the activity of some bimetallic catalysts, Platinum-based (PtM/CeZrO4, M=Re,La,Rh), highlighted the great ability of the Rhenium to enhance the activity and stability of the catalyst, even at very low temperatures. The effect of the preparation method, in terms of sequence of impregnation of the two active metals, was evaluated, showing a low impact on the performance of the final catalyst. The reported results indicate that the Platinum-Rhenium system represent a concrete possibility for the realization of a single stage WGS process.
