摘要：

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 H-2 flow. The samples were characterized by XRD, N-2 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 degrees C for DBT. The biphenyl (BP) selectivity was improved by adding the Co to the Ni2P/SBA-15/cordierite monolithic catalysts.
