Abstract
Adsorption and kinetic behaviors of thiophene, benzene, n-octane, and 1-octene in NaY, Ce(IV)Y, Ag(I)Y and Cu(I)Y have been investigated using a microgravimetric technique over a range of temperatures. The differences in isotherms, saturation adsorption capacities, isosteric heats of adsorption, entropies of sorbed phases and kinetics were discussed according to the different interaction mechanisms between the sorbates and the FAU zeolites. The dynamics and competitive adsorption of the above adsorbate mixtures have also been investigated. Ce(IV)Y has a very high selectivity to thiophene according to the kinetics of binary competitive adsorption of thiophene and benzene.
