Abstract

Abstract

The hydrotreating catalysts were prepared using Ni and W as active metals. The dispersity and sulfuration of the active metals were adjusted by adding organic modifiers to the Ni and/or W impregnation solution. Based on the experimental results, it was found that the dispersity of the active metals on the catalyst support was improved with organic modifiers dissolved in Ni and/or W impregnation solution. And increasing the amount of organic modifiers can not only increase the dispersity of main active phase WO₃ on the support, but also promote the formation of highly active nickel species in octahedral sites and of high hydrogenation phase NiWO₃. The calcination temperature can adjust the dispersity of active metals and acidity of the catalysts. The catalysts treated at optimized calcination temperature have appropriate ratio of weak and strong acidity sites and better hydrodesulfuration and hydrodenitrofication performance.
