Sturcture and Activity of Dispersed MoxW(1-x)S2 catalysts in Hydrocracking of Vacuum Residue |
| 초록 |
Catalytic activity and physical properties of the dispersed MoxW(1-x)S2 catalysts were investigated. The MoxW(1-x)S2 catalysts were prepared in situ in vacuum residue hydrocracking (VR HCK). Reaction tests were carried out in an autoclave batch reactor at 692K at 9.5MPa H2 with the same amount of catalyst loading of 0.113 mmol as a metal basis. The MoxW(1-x)S2 outperformed mono metallic sulfides of MoS2 or WS2 with a superior stability, demonstrating a synergic effects of the dispersed MoxW(1-x)S2 on the VR HCK. Extended X-ray absorption fine structure (EXAFS) and transmission electron microscopy (TEM) analysis were used to identify structure properties of the MoxW(1-x)S2 catalysts, which revealed that the dispersed MoxW(1-x)S2 may have a uniformly mixed structure of Mo and W rather than the core-shell structure. |
