Temperature dependence of rate constants on a per overall H+ site basis for (a) dehydrogenation and (b) cracking over H-FAU3.5 and H-FAU2.8 zeolites. Reaction conditions: H2/C3H8/Ar/He = 3/3/1.5/60, with a total pressure of 120 kPa and a total flow rate of 67.5 sccm, and space velocity = 3600 cm3C3H8·gcat−1 h−1, time-on-stream = 60 s. Propane conversions are <1%.
