Hydrotreating of non-edible Jatropha oil has a potential to become an important process for production of renewable and clean fuels. In the present work, a series of catalysts (NiMoP/Al_2O_3, NiMo/Al_2O_3-ZSM-5, NiMo/Al_2O_3-SiO_2, NiMo/Al_2O_3 and PtPd/Al_2O_3) were investigated in hydrotreating of Jatropha oil at 350℃, 3MPa and 2h^<-1> in a fixed-bed reactor. The relatiionship of catalytic actives and properties of catalysts were compared. Alkanes of straight chain C_<15-18> was the main products over low acidity catalysts, but the straight chain alkanes can undergo isomerization and cracking to produce lighter and isomerized alkanes at relatively high acidity catalysts. The reaction the deoxygenation of Jatropha oil via two different pathways: decarboxylation and hydrodeoxygenation. The metal center has a significant effect to the reaction pathway.
