The addition of Al2O3 up to 20% (as cementing agent) in SAPO-34 support significantly integrates metal functions of Pt-Sn-based catalyst, ultimately improves catalytic performance for direct propane dehydrogenation to propylene. Superior propane conversion (initially above 40%) and propylene selectivity (around 95%) is obtained experimentally over Pt-Sn/Al2O3-SAPO-34. The results were found promising and compared with Pt-Sn/SAPO-34 under identical operating conditions. Better platinum dispersion and higher active platinum sites are characterized by TEM and hydrogen-chemisorption analysis. Moreover, the possible metal interactions with different supports were configured. Therefore, light alkane dehydrogenation to alkene was enhanced using surface modified support Al2O3-SAPO-34 for Pt-Sn-based catalysts.
