Abstract

Abstract: W₂N/C catalyst for hydrodenitrogenation was prepared by the temperature programmed reaction. The effect of nitriding temperature on the catalyst activity was examined,and it was found that the optimum nitriding temperature was about 973 K.The law of pyridine hydrodenitrogenation over W₂N/C catalyst was investigited.Compared with WO₃/Cand WS₂/C which had the same precusor, W₂N/C had a higher catalytic activity and selectivity.The mechanism of pyridine hydrodenitrogenation over W₂N/C catalyst was put forward.

Key words: W₂N/C catalyst, Pyridine, Hydrodenitrogenation (HDN)
