Pt/Al{sub 2}O{sub 3}, Pd/Al{sub 2}O{sub 3}, and Pd/TiO{sub 2} catalysts were compared to a commercial hydrotreating catalyst, NiMo/Al{sub 2}O{sub 3}, for naphthalene hydrogenation inside tubing bombs at 553K with a cold feed (at room temperature) of 1000 psig H{sub 2} and tridecane as the solvent. The noble metal catalysts were found significantly more active than NiMo/Al{sub 2}O{sub 3}. A further study at a reaction temperature of 473K showed that naphthalene hydrogenation over these noble metal catalysts can proceed to almost completion even in the presence of benzothiophene to a sulfur content of 0.5% (wt). Pd/TiO{sub 2} catalyst was found to be the most active and the least affected by the sulfur compound among the three noble metal catalysts studied.
