Hensley, A L; Quick, L M

A heavy hydrocarbon stream containing metals, asphaltenes, nitrogen compounds, and sulfur compounds is (A) contacted with hydrogen and a hydrotreating catalyst containing molybdenum and chromium, either as metals, as oxides, as sulfides, or mixtures thereof, deposed on a large-pore, catalytically active alumina to reduce the metals content in said stream, to convert the asphaltenes, nitrogen compounds, and sulphur compounds in said stream, the catalyst has a pore volume within the range of about 4 cc/gm to about 0.8 cc/gm, a surface area within the range about 150 m/sub 2//gm to about 300 m2/gm, and an average pore diameter within the range of about 100 a (10 nm) to about 200 a (20 nm); and (B) at least a portion of the hydrotreated stream is cracked with a cracking catalyst to produce gasoline and distillates in improved yields. The catalyst in step (A) may also contain cobalt.
