ABSTRACT:
Heavy hydrocarbons are hydrotreated to increase content of components boiling below 1000.degree. F. by contact with Group VIII non-noble metal oxide and Group VIB metal oxide on alumina having a Total Surface Area of 175-220 m.sup.2 /g, a Total Pore Volume (TPV) of 0.6-0.8, and a Pore Diameter Distribution whereby .ltoreq.33% of the TPV is present as primary micropores of diameter .ltoreq.100 .ANG., at least about 41% of TPV is present as secondary micropores of diameter of about 100 .ANG.-200 .ANG., and about 16%-26% of the TPV is present as mesopores of diameter .gtoreq.200 .ANG.. Phosphorus containing compounds are avoided during catalyst preparation.
