Mo-Ni2P/SBA-15催化剂的制备、表征及加氢脱硫催化性能
Preparation, Characterization and Hydrodesulfurization Catalytic Performances of Mo-Ni2P/SBA-15 Catalysts
摘要
Abstract
A series of Mo-Ni2P/SBA-15 catalysts with various Mo loadings were prepared by impregnating nickel nitrate, diammonium hydrogen phosphate, and ammonium molybdate onto an SBA-15 support, fol owed by temperature-programmed reduction (TPR) under H2. The structure of the catalysts was characterized by X-ray diffraction (XRD), N2 adsorption-desorption, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The catalytic performance was evaluated in the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The results indicate that the mesoporous structure was maintained and the Ni2P phase was present in al of the catalysts. The chemical states of Ni were Niδ+and Ni2+, the chemical states of P were Pδ-and P5+, and the chemical states of Mo were Moδ+and Mo6+. Mo was shown to promote the HDS catalytic performance of Ni2P/SBA-15 catalysts. The Mo-Ni2P/SBA-15 catalysts with 1%(w, mass fraction) Mo loading exhibited the highest HDS activity. The conversion of the DBT reached 99.03%under reaction conditions of 380 °C and 3.0 MPa. The HDS of DBT proceeded mainly via the direct desulfurization (DDS) pathway over al of the tested Mo-Ni2P/SBA-15 catalysts.关键词
