Abstract

A complex metal oxide catalyst comprising a Group VIII metal MI and at least two Group VIB metals MII and MIII, wherein the molar ratio of Group VIII metal MI to Group VIB metals MII+MIII is 1:9-9:1 and the molar ratio of the Group VIB metals MII and MIII is 1:5 to 5:1. When applied to the hydrodesulfurization of diesel, the catalyst exhibits a super high HDS activity. The sulfur level in the diesel can be reduced from 1200 ppm to 27 ppm under a gentle operating condition.
