英文摘要: The effect of Mn doping on the adsorptive desulfurization performance of 5%Ni/ZnO adsorbents was investigated in model gasoline, with thiophene as a sulfur-containing compound, using a fixed-bed reactor. The 5%Ni/MnO-ZnO adsorbents with different levels of Mn doping were prepared using an incipient wetness impregnation method and characterized by powder X-ray diffraction (XRD). It was found that the adsorption performances of the 5%Ni/MnO-ZnO adsorbents were considerably improved after Mn doping compared with that of 5%Ni/ZnO. Moreover, the 5%NiO/MnO-ZnO adsorbents showed high desulfurization activities after regeneration. Sulfur removal by a 5%NiO/8%MnO-ZnO adsorbent after three reaction-regeneration cycles was 4% higher than that by a 5%NiO/ZnO adsorbent without Mn doping. The excellent performance of the 5%NiO/8%MnO-ZnO adsorbent in desulfurization, and its regenerability, were attributed to formation of a new compound, ZnMnO3, in the adsorbent; this compound as characterized using XRD.
