Traditional hydrocracking catalyst is to support the dual-function catalyst that Co (Ni)-Mo or Ni-W bimetal sulfide are made with the complex carrier that contains Y zeolite and aluminum oxide, and it is with hydrogenation and cracking function.Because the composition of catalyzer is similar to Hydrobon catalyst, this catalyzer also has certain hydrodesulfurization activity.But the hydrodesulfurization activity of traditional hydrocracking catalyst is all lower, is difficult to realize in same reactor simultaneously hydrocracking and hydrofining reaction.
It is generally acknowledged that the hydrodesulfurization activity of catalyzer is relevant with the dispersity of metal component, the high more hydrodesulfurization reaction activity of dispersity is high more.And the specific surface area of dispersity and catalyzer and pore volume are closely related, so the ideal carrier should have very high specific surface area.The scientist of U.S. Mobil company successfully synthesized a series of mesopore molecular sieves such as MCM-41 in 1992.With MCM-41 is example, and its aperture is adjustable between 1.5-10nm, and has very big surface-area (>1000m
