| 摘 要： | 制备了两个系列不同镍钼负载量的NiMo 催化剂,并用X 衍射、N2 物理吸附和透射电镜进行了表征。以二苯并噻吩 为模型硫化物,在高压固定床微型反应器上对该NiMo 催化剂的加氢脱硫性能进行了评价,研究了MoS2 形貌与催化剂加氢脱 硫选择性之间的关系。结果表明,镍钼负载量对MoS2 形貌有明显的影响。Mo18Ni4 催化剂(含18% MoO3 和4% NiO)上 MoS2 呈多级层状结构,具有较高的加氢脱硫活性和优异的加氢脱硫选择性。加氢选择性与催化剂上活性组分MoS2 的堆积层 数相关联呈很好的线性关系;堆积层数越多,其加氢选择性也越高。 |
| 关 键 词： | NiMo 催化剂 加氢脱硫 MoS2 形貌 加氢选择性 二苯并噻吩 堆积层数 |

| Abstract: | Two series of NiMo catalysts supported on alumina with different loadings of molybdenum and nickel were prepared and characterized by X-ray diffraction,N2 sorption,and high-resolution transmission electron microscopy.The performance of NiMo catalysts for hydrodesulfurization was evaluated in a fixed-bed microreactor using dibenzothiophene as a model compound.The effect of morphology of MoS2 phase in NiMo catalyst on its hydrogenation selectivity was investigated.The results indicated that the morphology of ... |
| Keywords: | NiMo catalyst hydrodesulfurization MoS2 morphology hydrogenation selectivity dibenzothiophene stacking number |
