Abstract
This chapter presents nuclear magnetic resonance (NMR) studies on the pyrrole adsorption over Na + -, Li + -exchanged zeolites of type FAU. Multinuclear solid-state NMR has been applied to study the interaction of pyrrole with extra framework compensating cations in zeolites LiNaY and LiNaX. Upon adsorption over zeolite LiNaY, Na + and Li + cations migrate toward accessible positions in the supercage to interact with one molecule of pyrrole. The adsorption over zeolite LiNaX decreases the mobility of SIII’ Na + cations while pyrrole molecules do not interact with Li + cations. At lower loading, pyrrole adsorbs over more basic sites, which are associated with Na + cations in zeolite LiNaY.
