Dehydrogenation of propane over Pt-SBA-15: Effect of Pt particle size

Studies on dehydrogenation of propane (DHP) over monometallic Pt-SBA-15 catalysts, which contain markedly different Pt particle sizes, reveal that the reaction is dependent on the size of the particle. Catalyst with smaller particles (∼3 nm) is much more active and less selective than that with larger particles (∼21 nm). Rate of coking, selectivity to coke formation and the amount of coke formed are significantly higher over the former than that on the latter.
