文章摘要

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.
