The removal of heteroatoms from naphtha using first row unsupported metal sulfide catalysts were completed. The maxima HDS activity, normalizing to the same weight of metal, is obtained for manganese sulfide while the minimum HDS activity is obtained for nickel sulfide. Chianelli et al. (1) reported that, for the first row transition metal sulfides, chromium sulfide has the highest activity for HDS of dibenzothiophene and manganese sulfide is the least active. The catalyst activity pattern of the first row transition metal sulfide for hydrodesulfurization of naphtha and dibenzothiophene is different. The maxima HDN activity, normalizing to the same weight of metal, is obtained for chromium sulfide and the minimum HDN activity is obtained for cobalt sulfide. The effect of substituents on the conversion of nitrogen compounds from the naphtha was also determined. The HDN conversion of alkyl-substituted pyridines and anilines are dominated by electronic effects rather than substituent effects. The effect of alkyl-substitution on the conversion of quinolines is relatively insignificant.
