Abstract
The process comprises contacting a heavy hydrocarbon stream containing metals and asphaltenes to reduce the contents of nitrogen compounds, sulfur compounds, metals and asphaltenes in the hydrocarbon stream under suitable conditions and in the presence of hydrogen with a catalyst comprising a hydrogenating component consisting essentially of molybdenum and chromium, their oxides, their sulfides, or mixtures thereof on a large-pore, catalytically active alumina. 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 to about 200 A.
