KINETIC-ANALYSIS OF N-TRIDECANE DESORPTION FROM TYPE 5A ZEOLITES

Kinetic parameters for desorption of n-tridecane adsorbed on commercia l 5A zeolite pellets have been measured. Pre-exponential factors, acti vation energies, and the populations of each binding state are reporte d. The results can be quantitatively fitted with a first order desorpt ion rate equation and three different desorption zones could be determ ined. The possible existence of a compensation effect is qualitatively discussed. Desorption rates for powder and pellets are compared and t he influence of initial coverage of pelletized zeolite on population a nd maximum temperature is presented.
