摘要
通过在载体SiO2 或Al2O3 上添加金属氧化物,制备了Pt-LaGaO3/SiO2、Pt-LaGaO3/Al2O3、Pt-LaAlO3/SiO2、Pt-La2O3/SiO2、Pt-Ga2O3/SiO2 系列Pt基催化剂,探索金属氧化物的修饰对Pt活性中心丙烷脱氢性能的影响.实验结果表明,使用具有适宜组成和结构的复合金属氧化物修饰Pt催化剂,可以极大提高催化剂的丙烷脱氢性能.
Abstract
A series of Pt-based catalysts,including Pt-LaGaO3/SiO2,Pt-LaGaO3/Al2O3,Pt-LaAlO3/SiO2,Pt-La2O3/SiO2 and Pt-Ga2O3/SiO2,were prepared by adding metal oxides to the support SiO2 or Al2O3.The effect of metal oxide modification on the propane dehydrogenation performance of Pt active centers was investigated.The experimental results indicate that the composite metal oxide-modified Pt catalysts with suitable composition and structure can greatly improve the propane dehydrogenation performance of the catalyst.
