Inverse gas chromatography parameters

Inverse gas chromatography parameters can also be applied in the field of cafaly-sis. In fhis way, as example, parent NaX and CaA zeolites, as well as transition metal (Co +, Mn +, Fe " )-exchanged zeolites, were evaluated for the catalytic oxidation of n-hexane. It was observed [51, 52], that although there was linear correlation between the acidity and the adsorption enthalpy of the n-hexane, there was no relationship between the acidity and the activity for n-hexane oxidation. However, if a reactivity parameter (such as Tso, temperature at which 50 % of conversion is attained) is plotted versus the adsorption heat, a so-called Volcano plot is obtained (Fig. 16.12), an optimum value of (-AH ) being observed, higher and lower values yielding to worst catalytic performance.
