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

Abstract

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 hydrodenitrogenation ability of Al-SBA-15 supported Mo–Ni catalysts.
