【摘要】 通过改变金属负载量得到一系列不同性质的NiMo/Al₂O₃催化剂,定量研究NiO负载量、MoO₃负载量和MoS₂晶簇表面有效Mo原子分散度3个变量对加氢脱硫（HDS）活性的影响规律。运用"动态超几何平均"的方法对已提出的模型进行修正,建立了二苯并噻吩HDS转化率与催化剂性质的定量关系模型。结果表明:所提出的模型对实验数据拟合的平均相对偏差仅为1.13%;用所建立的模型计算得到最佳的NiO负载量（w）为3%⁴%,MoO₃负载量（w）为12%¹4%;Mo原子分散度对催化剂的活性具有正面影响;催化剂HDS活性对NiO含量更敏感。更多还原

【Abstract】 A series of NiMo/Al₂O₃ catalysts with different properties was obtained by controlling the metal loading.NiO loading,MoO₃ loading and the MoS₂ dispersion of the catalysts were considered and a"dynamic super geometric average"was applied to revise the existing model to establish a quantitative relationship between the catalyst properties and the HDS conversion rate.The results indicated that the average relative deviation for the modified model is only 1.13% .The optimum MoO₃ and NiO loadings are 12% —14% and 3% —4% ,respectively,as analyzed by the established model.The results also showed that hydrodesulfurization activity is more sensitive to the content of NiO loading.更多还原
