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, ruand rh) nanocatalysts that is used for the catalytic hydrogenation of benzene in gasoline. metal catalystswere then loaded with the impregnation method and deposited on the functionalized fullerene. responsesurface methodology (rsm) was used to investigate the cumulative effect of various parameters includingpressure, temperature, time and loading and to optimize these parameters to maximizing the hydrogenationof benzene in gasoline. the catalysts were characterized before reaction by xrd, tem and tga. theresults show that the yield of hydrogenation under optimum conditions (include metal loading of about10%, reaction time of 180 min and hydrogen pressure of 50 atm) are obtained: 99.59, 99.48, 98.09, 98.51and 97.56%, for rh, ru, pt, pd and ni, respectively. these results are obtained by the diffrent reactiontime for rh, ru, pt, pd and ni following: 180, 125, 31.25, 180 and 180 min respectively.
