Abstract
An unsupported multi-metallic layered catalyst which comprises two or more Group VIB metals, one Group VIII metals, and one divalent metal, is used in ultra-deep hydrodesulfurization of diesel. And on oxide basis, it comprises 1-50 wt % Group VIII metals, 1-50 wt % divalent metals, and 5-60 wt % two Group VIB metals. Under hydrodesulfurization conditions, it can reduce sulfur content (in the form of 4, 6-DMDBT) of diesel from 500 wppm to less than 10 wppm. Besides, it also lowers the cost of catalysts.
