Thecatalyticactivityofmolybdenumcarbide(MoCx),nitride(MoNx),andphosphide(MoPx)wascomparedinthe hydrotreatment of rapeseed oil performed in a continuous fixed bed reactor at 350–390°C, 5.5MPa andvarious Weight Hourly Space Velocities (WHSV). The deoxygenation activity was in the following order:MoCx > MoNx > > MoPx. In the case of MoCx, the temperature increase resulted in a decrease of thedeoxygenationactivityduetothecompetitivehydrocracking.Wherein,MoNxshowedthehighesttendencytohydrocrackingandverystrongeffectofWHSVat350°C,whichthenbecamelesssignificantathigherreactiontemperatures.WhileMoPxactivitywasstronglyinfluencedbythemasstransferlimitations.1.
