Abstract Desulfurization of high sulfur-containing diesel(mass fraction of(1 600)×10~(-6)) by different Cu~(2+) zeolites was analyzed in a fixed-bed adsorber.The zeolites were prepared by both direct synthesis and ion-exchange methods with HZSM5,then used for adsorption desulfurization of diesel fuel at room temperature and atmospheric pressure.The CuMCM41 adsorbent is capable of treating 5 mL of high sulfur-containing diesel fuel per gram of adsorbent,desulfurizing the diesel to concertrations less than 300×10~(-6)(mass fraction).These sorbents have been proven to have high sulfur-selective ability.CuMCM41 was used to adsorb model diesel,the results showed that CuMCM41 adsorbed more thiophenes and benzothiophene than naphthalene from model diesel.
