| Description |
The acidity and acid strength distribution of chlorided y-aluminas and mono and
bimetallic catalysts containing Pt and Sn metals supported on a chlorided y-AhO3 were
measured by micro calorimetry and temperature programmed desorption (TPD) techniques.
The addition of chlorine to y-AhO3 creates new stronger acid sites. The total acid site
density also increases with increasing chlorine content in the alumina support. The addition
of tin to chlorided alumina suppresses the stronger acid sites. The catalytic activity for
dehydration and dehydrogenation of 2-propanol on these catalysts was evaluated. A
correlation between strong acid sites and dehydration activity was established.
Keywords.. Acidity, Microcalorimetry, Temperature programmed desorption, Catalytic
reforming and Pt-Sn/AlzO3.
