Application of palladium supported on functionalized MWNTs for oxidative desulfurization of naphtha
Neda Mohammadi Meman,Bahman ZareNezhad,Alimorad Rashidi,Zeinab Hajjar,Elaheh Esmaeili 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.22 No.-
In this research, Pd supported multi wall carbon nanotube(MWNT) nano catalyst prepared in previouswork used for investigation the efficiency of an oxidative desulfurization (ODS) process in sulfurreduction from naphtha. Palladium (Pd) supported on functionalized multi-walled carbon nanotubes(FMWNTs) have been found to be effective in catalyzing oxidation of the sulfur impurities in naphtha tocorresponding sulfones. a catalyst of 0.1%wt Pd on FMWNT as a support synthesized by impregnationmethod and was characterized by TEM, X-ray Diffraction (XRD), TPR and BET analysis. oxidativedesulfurization reaction was done at 25 8C in atmospheric pressure under reaction condition of VH2O2 =2 mL and Fuel/solvent molar ratio = 2.We also applied our catalyst in oxidative desulfurization reactionof naphtha (with sulfur contents 870 ppm), and more than 90% of sulfur was removed from naphthaunder mild reaction conditions.
