摘要/Abstract

摘要： 采用水热合成法制备了棒状CuO-ZnO复合氧化物，采用等体积浸渍法制备了Ni/CuO-ZnO吸附剂，采用TG、SEM，XRD，BET方法进行了表征。在固定床反应器中进行了吸附剂的反应吸附脱硫性能评价。结果表明：制备的CuO-ZnO复合氧化物呈棒状结构，复合氧化物适宜的焙烧温度为500 ℃；Cu的掺杂有效改进了反应吸附剂的脱硫性能，Cu的最佳掺杂量（w）为10%，掺杂Cu后脱硫率较Ni/ZnO平均脱硫率提高17.4百分点，且能延长有效脱硫时间，吸附剂在45 h左右仍能保持较高的脱硫活性。

Abstract: The rodlike CuO-ZnO complex oxides were prepared by hydrothermal synthesis method. The adsorbents of Ni/CuO-ZnO were prepared by incipient-wetness impregnation method. The complex oxides and the adsorbents were characterized by TG，XRD, SEM and BET techniques. The performance of reactive adsorption desulfurization for thiophene was evaluated in a fixed bed reactor. The results indicate that the suitable calcination temperature for composite oxides and Ni/CuO-ZnO is 500 ℃. The doping of Cu effectively improves the reactive adsorption desulfurization performance, and the adsorbent with 10% CuO shows the best desulfurization activity, 17.4 percentage points higher than the reference Ni/ZnO. And the adsorbent with Cu doping is more stable, the adsorbent still remain high desulfurization activity in 45 hour.
