摘要:
Ni-promoted tungsten catalysts are widely used for hydrotreating various petroleum fractions. The catalysts have to be sulphided prior to use in industry, because sulphided catalyst has higher activity and more stability. The influence of the sulphiding conditions on the performance of WNi/Al2O3 has been investigated by some reseachers[1] except for WNi/USY+Al2O3 hydrocracking catalyst. In this paper, the optimal sulphiding conditions of WNi/USY+Al2O3 have been studied by XPS.
