Hydrogenation of benzene in gasoline fuel over nanoparticles (Ni, Pt, Pd, Ru and Rh) supported fullerene:Comparison study



The main purpose of the present study is to synthesis different fullerene (C60)-based metal (Ni, Pd, Pt, Ru and Rh) nanocatalysts that is used for the catalytic hydrogenation of benzene in gasoline. Metal catalysts were then loaded with the impregnation method and  deposited on the functionalized fullerene. Response surface methodology (RSM) was used to investigate the cumulative effect of various parameters including pressure, temperature, time and loading and to optimize these parameters to maximizing the hydrogenation of benzene in gasoline. The catalysts were characterized before reaction by XRD, TEM and TGA. The results show that the yield of hydrogenation under optimum conditions (include  metal loading of about 10%,  reaction time of 180 min and hydrogen pressure of 50 atm) are obtained: 99.59, 99.48, 98.09, 98.51 and   97.56%, for Rh, Ru, Pt, Pd and Ni, respectively. These results are obtained by the diffrent reaction time for Rh, Ru, Pt, Pd and Ni following: 180, 125, 31.25, 180 and 180 min respectively.
