| 英文摘要 | the effect of zno particle size on the adsorptive desulfurization performance for ni/zno (5 wt% nio) adsorbent was investigated using thiophene as a sulfur containing compound in model gasoline with a fixed bed reactor. the ni/zno adsorbents with different zno particle sizes (8, 12, 20, 30 nm) were prepared by an impregnation method and characterized by powder x-ray diffraction (xrd), high resolution transmission electron microscopy (hrtem) and transmission electron microscopy (tem). it was found that the adsorption capacity of the ni/zno adsorbent for thiophene significantly increased with the decrease of the zno particle sizes. typically at a breakthrough sulfur level of 1 mg/l, sulfur capacity of ni/zno (8 nm) from model gasoline (500 mg/l) is much higher than that of ni/zno (30 nm) from 84 mg sulfur per gram adsorbent to nearly 0 mg sulfur per gram adsorbent. this higher desulfurization activity and sulfur capacity for ni/zno with smaller zno particle sizes could be derived from higher ni dispersion on zno and lower mass transfer limitations of sulfur to zno from ni in h-2.
