摘　　要：用吡啶 -TPD实验和异丙醇分解反应研究了稀土助剂Y对甲烷芳构化反应催化剂Mo/HZSM - 5表面性质的影响 ,说明了稀土Y对Mo/HZSM - 5催化剂的添加增强了催化剂表面的酸性 ,从而促进了甲烷的活化 ,提高了甲烷转化率。The fluence of rare earth additive Y on surface characteristics of methane aromatization Catalyst Mo/HZSM-5 by pyridine-TPD experiments and isopropyl alcohoc decomposition reaction has been studied.It shows that addition of rare earth Y can increase calatyst surface acidity to Mo/HZSM-5 catalyst.It promotes activation of methane and increases conversion rate of mathane.
