摘要：

Isomerization-cracking of n-octane was studied using H3PW12O40 (HPA) and HPA supported on zirconia and promoted with Pt and Cs. The addition of Pt and Cs to the supported HPA did not modify the Keggin structure. The Pt addition to the supported HPA did not substantially modify the total acidity; however, the Bronsted acidity increased significantly. Cs increased the total acidity and Bronsted acidity. A linear relation was observed between the n-C-8 total conversion and Bronsted acidity. The most adequate catalysts for performing isomerization and cracking to yield high research octane number (RON) are those with higher values of Bronsted acidity.
