Abstract
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 0.4 cc/gm to about 0.8 cc/gm, a surface area within the range of about 150 m.sup.2 /gm to about 300 m.sup.2 /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.
