| Abstract: | Mg-, Mn-, Co- and Zn-substituted AlPO-11 molecular sieves were synthesized, characterized and used as acidic supports of the bifunctional Pt/MeAPO-11 catalysts in the hydroisomerization of n-dodecane. As compared to AlPO-11, the acidity of MeAPO-11 increased considerably, while the metallic properties of Pt over MeAPO-11 was weakened, especially for Mn- and Co-containing catalysts. In the hydroisomerization of n-dodecane, the activity of Pt/MeAPO-11 was primarily determined by the acidic strength of MeAPO-11, whereas the isomerization selectivity was controlled by the combined effect of the acidity of MeAPO-11 and the (de)hydrogenation function of Pt. |
