AbstractZeolites NaY and LaNaY (ion-exchanged with aqueous lanthanum nitrate solution) were used as adsorbents for removing organic sulfur compounds from model gasoline solutions (without and with toluene) and fluid catalytic cracked gasoline in fixed-bed adsorption equipment at room temperature and atmosphere pressure. The adsorptive selectivity for organic sulfur compounds was significantly increased when Na+ ions in zeolite NaY were exchanged with lanthanum ions. IR spectra of thiophene adsorption indicate that thiophene is adsorbed onto La3+ ions via direct S-La3+ interaction and Na+ ions via pi-electronic interaction for La3+-exchanged zeolite NaY, but only via pi-electronic interaction with Na+ ions for NaY. The amount of adsorbed thiophene on La3+-exchanged zeolite Y was slightly decreased by coadsorption of benzene, but greatly reduced on NaY. The adsorption of thiophene via interaction with La3+ on La3+-exchanged zeolite Y is hardly replaced by benzene coadsorption. The direct S-La3+ interaction might be the essential reason for the evidently improved adsorptive selectivity of LaNaY for removing organic sulfur compounds from solutions containing large amount of aromatics.
