摘　　要：以等体积浸渍法制备了负载型NiO/γ-Al2O3吸附剂,在固定床反应装置上对含苯并噻吩的模型化合物进行反应吸附脱硫实验,考察了NiO负载量、模型化合物硫含量及活性组分的形态对吸附剂脱硫性能的影响,并用XRD、SEM-EDS分析、XPS分析对载体和吸附剂进行了表征。实验结果表明:NiO/γ-Al2O3吸附剂具有较高的穿透硫容,能有效脱除模型化合物中的苯并噻吩;反应过程中生成了NiS;C的沉积以及Ni的硫化物的生成导致了吸附剂的失活。NiOγ/-Al2O3 adsorbent was prepared by wet impregnated method. Reactive adsorption desulfurization of model sulfur compound was conducted in a fixed-bed reactor. The influences of loading content of NiO, sulfur concentration of model compounds and the status of active particles on the desulfurization performance were investigated. The carrier and prepared adsorbents were characterized by means of the techniques such as XRD, SEM-EDS and XPS. The results showed that NiOγ/-Al2O3 adsorbent had higher breakthrough sulfur capacity, and it could remove benzothiophene from model sulfur compound effectively. NiS were formed in the process of reaction. NiOγ/-Al2O3 adsorbent was inactivated because of the deposition of C and formation of NiS.
