摘要
通过程序升温还原法和原位傅里叶红外光谱方法，研究了钼镍系列加氢处理催化剂的还原性质和酸性质．以噻吩为探针分子，用脉冲微反方法研究了该催化剂的加氢脱硫性能．研究表明，第三组分（如ＴｉＯ２、Ｐ２Ｏ５）的加入，引起了该催化剂的表面酸性质和加氢脱硫性能的变化．
he reduction and acidity properties of nickel-molybdenum hydrotreating catalysts have been studied by TPR and in situ FTIR. The hydrodesulfurization activity has been studied by pulse micro-reaction method using thiophene as probing molecule.The results show that the addition of third component (like TiO2,P2O5) will change the surface acidity and the activity of hydrodesulfurization of these catalysts.
