Adsorption of binary gases (CH 4 / CO, CO/ NO, and CO/CO 2 ) sorbing almost all of the adsorbate. Using this method, on alkali metal (Li, Na, K, Rb, and Cs) ion-exchanged ZSM-5 Hampson et al. studied coadsorption of ethane and propane zeolites were studied using IR spectroscopy. IR absorption bands on silicalite-1 and NaY zeolite, and concluded that NaY of preadsorbed CH 4 , particularly that of n 1 (induced band), dezeolite would be one of the most efficient adsorbents for a creased with the increase in the partial pressure of CO, indicating separation process of light hydrocarbons by the pressure the preferential adsorption of CO on the cation site of zeolite. In swing adsorption method (4).
addition, IR band profiles of adsorbed CO changed in a different
However, information obtainable from a volumetric or a manner when CH 4 , NO, or CO 2 was added to the system, suggravimetric adsorption measurement combined with thermogesting that the selectivity of adsorption was governed not only by the polarity of adsorbates but also by the nature of sites present dynamical analysis is rather limited and one cannot avoid in the ZSM-5 pore bearing different electric field strengths. แญง 1998 some assumptions when deducing the state of admolecules Academic Press
