ABSTRACT:
A mild hydrocracking process for the hydrodemetallation (HDM), hydrodesulfurization (HDS) and hydroconversion (HC) of hydrocarbon feedstocks such as residuum feedstocks which provides increased conversion of the 1000.degree. F.+ hydrocarbon fraction to the 1000.degree. F.- fraction and increased yields of middle distillates is disclosed. The process utilizes a catalyst comprising about 2.0 to about 6.0 wt. % of an oxide of a Group VIII metal, about 12.0 to about 25.0 wt. % of an oxide of molybdenum and 0 to about 3.0 wt. % of an oxide of phosphorus supported on a porous alumina support containing about 4.0 to about 30 wt. % of silica.
