| 摘 要： | 在全硅介孔分子筛SBA-15材料合成的基础上由Al2O3、BaO和K2O改性合成了Al2O3-SiO2 、BaO-Al2O3-SiO2和K2O-Al2O3-SiO2介孔复合氧化物，通过低温N2吸附、XRD、电镜等表征发现它们具有与SBA-15相似的有序介孔孔道结构。同时考察了由它们制备的Pt/MxOy-SiO2催化剂的正己烷芳构化性能，发现Pt/MxOy-SiO2催化剂具有较好的芳构化性能，其芳烃产率和液体收率都高于传统铂铼重整催化剂。

| Abstract: | Al2O3-SiO2, BaO-Al2O3-SiO2 and K2O-Al2O3-SiO2 mesoporous mixed-oxides were synthesized according to the synthesis procedure of mesoporous silica material SBA-15 and with the involvement of Al2O3, BaO and K2O. The obtained materials were characterized by XRD, N2 adsorption-desorption and TEM techniques. Their catalytic performances for hexane aromatization were investigated. Results showed that these materials possessed the similar highly ordered mesoporous pore structure as SBA-15 had; as compared with the conventional industry reforming catalyst, Pt/MxOy-SiO2 catalysts exhibited excellent catalytic performance high in liquid yield and aromatics yield. |
