Noble metal on rare earth modified silica alumina as hydrocarbon conversion catalyst |
摘要 |
Rare earth oxides, such as Nd2O3 disperse onto the surface of SiO2/Al2O3 and act as weakly basic titrants. This lowers the acidity of SiO2/Al2O3 to close to that of chlorided alumina, as shown by model compound reaction tests. This support also disperses a noble metal such as Pt much better than undoped SiO2/Al2O3 and similar to chlorided alumina. Platinum on the rare earth modified silica alumina can function as a hydrocarbon conversion catalyst in reactions where Pt/chlorided Al2O3 is used, such as in reforming, and isomerization, especially wax isomerization.
