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.
