摘要
The catalytic Performance and the properties of active sites On PtY/Al2O3 have been studied using a pulse microreactor, TEM and Poisoning technique. The study shows that PtY/Al2O3 shows higher activity and selectivity for n-hexane conversion and the dehydrogenation of cyclohexane, as compared to Pt/Al2O3. The changes in PtY/Al2O3 geometric patterns and in both the total numbers of active sites (TNAS) and the active site distribution (ASD) caused by Y are likely to be responsible for the catalytic improvements.
