A series of MCM 41 mesoporous molecular sieves with different SiO 2/Al 2O 3 molar ratios were synthesized by hydrothermal method. The influence of aluminum content on the properties of MCM 41 was investigated. Ni Mo P catalysts were prepared by impregnating HY/MCM 41/γ Al 2O 3, HY/γ Al 2O 3 and γ Al 2O 3 with Ni Mo P solution, and the catalytic activity of sulfided Ni Mo P catalysts was evaluated by naphthalene hydrogenation. The results showed that the crystallinity of MCM 41 decreased with the increase of aluminum content. However, the hydrogenation activity, especially the ring opening activity, of the catalyst increased with the aluminum content. The catalyst using HY/MCM 41/γ Al 2O 3 as support showed a synergistic effect and higher catalytic activity for naphthalene hydrogenation. The reaction mechanism was proposed, and the reaction network for naphthalene hydrogenation might include two parallel pathways: naphthalene was hydrogenated to tetralin, and then the isomerization and ring opening of tetralin occurred, or tetralin was further hydrogenated to decalin followed by the isomerization and ring opening of decalin.
