Methyl ester and triglyceride hydrodeoxygenation studied by sulfided NiMoS/Al₂O₃.

Hydrolysis ester in triglycerides easier than in methyl esters, catalyzed by Al₂O₃.

Different active sites for hydrodeoxygenation and decarbonation.

Hydrogenation activity decreases stronger than deoxygenation activity.

Metal sulfide stable, deactivation due to heavy product deposition.
