摘要：Phosphorous-modified MoO3/SiO2 catalysts with various P/Mo molar ratios (MoPxO/SiO2, x = 0.3 - 3.0) were prepared by co-impregnation and compared with MoO3/SiO2 in the oxidation of dibenzothiophene by cumene hydroperoxide. The addition of P significantly enhanced the catalytic performance, and MoP1.0O/SiO2 exhibited the highest oxidation activity. XRD characterization indicated that the active phase of MoP1.0O/SiO2 was amorphous, whereas P-31-NMR measurements revealed that MoP1.0O/SiO2 had a similar connectivity of Mo-O-P to H3PMo12O40. The total sulfur of a hydrotreated diesel was reduced from 298 to 5 ppmw by oxidation with CHP and subsequent dimethylformamide extraction. (C) 2013 Elsevier B.V. All rights reserved.
