摘　　要：以盐酸处理后的活性炭(AC)为载体制备了负载金属钯的PdCl2/AC吸附剂,用于对柴油中的噻吩进行吸附脱硫,并考察了CuCl2的加入量对PdCl2/AC吸附剂脱硫率的影响。结果发现:当Cu与Pd的摩尔比为2∶1时,制备的吸附剂对模型油中噻吩的脱除率达95.7%,明显高于未负载的活性炭。采用SEM及XRD对吸附剂进行了表征,并对吸附机理和吸附等温线进行了初步探讨。The adsorbent PdCl2/AC is prepared by loading Pd on activated carbon （AC） modified by HCl and applied in removal of thiophene from diesel. The influence of addition of CuCl2 on the sulfide removal rate of PdCl2/AC is investigated. The results show that when the molar ratio of Cu to Pd is 2 ： 1, the sulfide removal rate of prepared adsorbent CuCl2-PdCl2/AC reaches to 95.7%, which obvious higher than that of activated carbon without loading. The adsorbent is characterized by SEM and XRD, and the adsorptive mechanism and adsorption isotherm are discussed.
