The study of the removal of heteroatoms from naphtha using second row unsupported metal sulfide catalysts was completed. For the HDS reaction, the maximum and minimum % sulfur removal, based on three grams of catalyst, is obtained for molybdenum sulfide and niobium sulfide, respectively. Chianelli et al.(l) reported for the second row transition metals that ruthenium sulfide has the highest activity for HDS of dibenzothiophene and zirconium sulfide has the lowest activity. The maximum activity for HDN, based on three grams of catalyst, is obtained for molybdenum sulfide and the minimum activity is obtained for niobium sulfide, just as was the case for the HDS reaction. A HDS of dibenzothiophene was carried over the unsupported second row transition metal sulfides following the procedure of Chianelli (1). The results show that the transition metal sulfides prepared at the CAER were similar in activity for HDS of dibenzothiophene as those prepared by Chianelli at al.(1).
