Resumen

Vanadium nitride and carbide were synthesized by the temperature-programmed reaction of ammonium vanadate (NH₄VO ₃) with pure NH₃ and 20% CH₄ in H₂, respectively. Based on the XRD results, the catalysts showed VN and V ₈C₇/V₄C₃ with an amount of V ₂O₃ in the bulk after nitridation and carburization. The hydrogenation, hydrodesulfurization and hydrodenitrogenation reactions were studied and compared to vanadium sulfide catalyst. These catalysts (VC, VN) are stable under typical hydroprocessing conditions.
