摘      要：Desulfurization of gasoline distillation with adsorption was studied at ambient temperature and pressure by using CuNaY（NaY exchanged with copper nitrate aqueous solution） as the *** gasoline distillation was composed of thiophene-cyclohexane solution（115.0 μg/mL） with or without *** the solution without toluene,no detectable sulfur was found in the effluent when the effluent volume was less than 40 mL,while the addition of toluene resulted in an evident drop of the adsorption performance for（CuNaY.） FTIR spectra indicate that the conversion of Cu2+ to Cu+ took place during the pretreatment of（CuNaY） adsorbent,and the interaction mode between the adsorbed thiophene molecules and Cu+ is π *** adsorption mode is easily affected by aromatic compounds,resulting in the significant decrease of adsorption capacity in model gasoline containing toluene on CuNaY.
