Five adsorbed systems have been studied by using exponential heating desorption. Those are benzene/zeolite HZSM-5, benzene/zeolite NaY, benzene/zeolite rare-earthe-Y, benzene/mordenite and n-hexane/mordenite. The experiments proved that the relation between activation energy of desorption and temperature of most desorption rate is linear, i.e. E_d=KT_m.
The data of exponential temperature programmed were analysed and compared with those of linear temperature programmed. The values of various kinetics parameter are coincided. Their activation energies are shown in Table.
The following kinetics parameter equation of exponential temperature programmed has been derived:
lnT_m/a=E_d/RT_m+lnE_d/ARnθ_m~(n-1).
and the equation has compared with that of linear temperature programmed:
lnT_m~2/β=E_d/RT_m+lnE_d/ARnθ_m~(n-1).| It is found that the effect of temperature deviation, ΔT, on all parameter is less (2T+ΔT) times by using equation of exponential temperature programmed than that of linear temperature programmed.
Through these experiments we found that the temperature control of exponential temperature programmed is easier than that of linear temperature programmed.
