Mo-Ni/Al-SBA-15 (Sulfide) Catalysts for Hydrodenitrogenation: Effect of Si/Al Ratio on Catalytic Activity

Mesoporous Al-SBA-15 with different Si/Al molar ratio (10, 20, 30, and 40) was synthesized hydrothermally, and Mo-Ni catalysts were prepared by incipient wet impregnation method and characterized by different techniques. An impressive catalytic performance was observed on Mo-Ni/Al-SBA-15(10) for Methylcyclohexylamine conversion to hydrocarbons. The observed trend of activity is correlated with the aluminum content, and it is concluded that the variation in Si/Al ratio remarkably affects the hydro-denitrogenation ability of Al-SBA-15 supported Mo-Ni catalysts.
