摘　　要：To investigate the effect of texture structure on the desulfurization performance in the Ni/ZnO reactive adsorption desulfurization（RADS） system,two kinds of ZnO porous materials with rod-shaped morphology were synthesized and their structure was characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,and N2 adsorption/desorption.The formation mechanisms of hierarchical porous ZnO（ZnO with meso and macro pores） were also studied.Their application performance was evaluated in the RADS process over Ni/ZnO absorbent.Due to the difference in structure between the two kinds of ZnO,the two ZnO based adsorbents showed different desulfurization activity.To investigate the effect of texture structure on the desulfurization performance in the Ni/ZnO reactive adsorption desulfurization（RADS） system,two kinds of ZnO porous materials with rod-shaped morphology were synthesized and their structure was characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,and N2 adsorption/desorption.The formation mechanisms of hierarchical porous ZnO（ZnO with meso and macro pores） were also studied.Their application performance was evaluated in the RADS process over Ni/ZnO absorbent.Due to the difference in structure between the two kinds of ZnO,the two ZnO based adsorbents showed different desulfurization activity.
