Gas phase hydrogenation of toluene by Pt, Rh, Pd and bimetallic alumina supported catalysts at mild temperature

Abstract EN

In the hydrogenation of toluene by alumina supported Pt, Pd and Rh; Rh/AUOg was found to be the most active.

Over Rh/A^Oj and at a temperature lower than 80 °C, hydrogenation can be done effeciently.

Meanwhile hydrogenation by Pt/A^Og attains a toluene conversion of 3% at 25 °C and RI1/AI2O3 attains a conversion of 43% at the same temperature, Pt/A^Oj does not show any activity at this temperature.

However, the bimetallic catalyst Rh-Pt/AbO-^ at all composition ratios used in this study shows the highest activity among used catalysts at the same reaction conditions.
