An increase in the Sn/Pt ratio will further reduce the particle size of Pt and increase its dispersion. When the Sn/Pt ratio is 1.5, it shows the best catalytic activity. The metal particle size of the catalyst has a great influence on the dehydrogenation process of methylcyclopentane (MCP), showing an obvious size effect.

Propane dehydrogenation on Pt–Sn/Al 2 O 3 and Pt–Sn/ZnAl 2 O 4 was performed, and the Pt–Sn/ZnAl 2 O 4 catalyst showed a stronger tolerance for catalytic deactivation than the Pt–Sn/Al 2 O 3 catalyst. In this study, we propose that the high catalytic stability of Pt–Sn/ZnAl 2 O 4 originates from the relatively faster coke mobility …
