• A not negligible homogeneous reactions contribute is observed, due to
the reactor configuration
• Minimization of reactants residence time at high temperature out
of the catalytic volume
• Platinum shows an evident contribute in catalyst activity
• Tin catalyst decreases catalyst deactivation rate
• A relevant coke formation was observed in all the catalytic
configurations
• Lower temperature tests shows a very lower propane conversion, but a
sensible improvement in propylene selectivity
