W2N／C催化剂加氢脱氮的研究
Investigation of Hydrodenitrogenation on Activated-Carbon-Supported Tungsten Nitride Catalyst
【摘要】 制备了加氢脱氮高活性催化剂Ｗ２Ｎ／Ｃ，探讨了氮化温度对催化剂活性的影响，考察了Ｗ２Ｎ／Ｃ催化剂上吡啶的加氢脱氮规律，提出了在该催化剂上吡啶加氢脱氮反应机理。
【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/C and 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.
