| 摘 要： | 用共浸渍法制备了Co-Ni2P/SBA-15前躯体,将其调制成活性胶后均匀涂覆到预处理后的堇青石载体上,程序升温还原后制备了一系列Co-Ni2P/SBA-15/堇青石整体式催化剂。采用XRD、N2吸脱附和XPS等对催化剂进行了表征,以1 wt%二苯并噻吩(DBT)/十氢萘溶液为模型化合物,在微型固定床反应器上对催化剂的加氢脱硫(HDS)性能进行了评价。结果表明,不同Co含量的Co-Ni2P/SBA-15/堇青石整体式催化剂中都形成了Ni2P相。Co的加入提高Ni2P/SBA-15/堇青石催化剂的比表面积和孔体积。Co含量为0.55wt%的Co-Ni2P/SBA-15/堇青石整体式催化剂有最好的二苯并噻吩加氢脱硫活性,在380℃,二苯并噻吩转化率能够达到98.8%。Co的加入能够提高二苯并噻吩直接加氢脱硫产物联苯的选择性。 |

| Abstract: | A series of Co-Ni2P/SBA-15/cordierite monolithic catalysts were prepared by coating the slurry of the Co-Ni2P/SBA-15 precursors on a pretreated cordierite support,and followed by temperature-programmed reduction in a H2 flow.The samples were characterized by XRD,N2 adsorption-desorption and XPS.The catalytic activities for the hydrodesulfurization(HDS) of dibenzothiophene(DBT) were evaluated.The results showed that Ni2P phase was present in the all Co-Ni2P/SBA-15/cordierite monolithic catalysts.The surface areas and pore volume of the Co-Ni2P/SBA-15/cordierite monolithic catalysts slightly increased when Co was added to the Ni2P/SBA-15/cordierite monolithic catalyst.The Co-Ni2P/SBA-15/cordierite monolithic catalyst with Co loading of 0.55wt% exhibited the highest conversion of 98.8% at 380 ℃ for DBT.The biphenyl(BP) selectivity was improved by adding the Co to the Ni2P/SBA-15/cordierite monolithic catalysts. |
