Abstract:
To check coke formation on metallic (Pto) and acidic (Al3+) centers of Pt/Al2O3 and Pt−Sn/Al2O3 catalysts, the application of IR spectroscopy of adsorbed CO for detecting Pto−CO (2070 cm−1) and Al3+−CO (2190 cm−1) bonds has been substantiated. Decrease in the number of active Pto and Al3+ centers is shown to correlate with that in the dehydrogenation rate of cyclohexane and in the isomerization rate of heptane, respectively.
