Hydrodeoxygenation of oleic acid, a model compound representing Canola oil (real feed stock) was performed using series of mesoporous supported metal nitride catalysts over  reaction temperature range of 350-410�C and hydrogen pressure maintained at 6.55 MPa. Reactions were carried out in a batch reactor setup with maximum reaction time of 8h. Nitrides of vanadium, tungsten and molybdenum supported on commercial Al2O3 and nitrides of Ni-Mo supported on Al2O3, SBA-15 and HMS were evaluated for their hydrodeoxygenation activity in terms of extent of oxygen removal. All the catalysts were prepared by impregnation method with same metal loading (12 wt. % Mo and 4 wt. % Ni). Characterization results indicate that NiMo/Al2O3 had the highest surface area (205 m2/g) and average pore diameter of 10.2 nm. XRD results indicated that the active metals were dispersed well as no significant peaks at expected 2? values were observed. Ni-Mo supported over Al2O3 gave maximum oxygen removal of 77% and alkane (C14-C18) selectivity of 42% proving it superior over other catalysts evaluated.
