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 VI-B metal oxide on alumina having a Total Surface Area of 150-240 m.sup.2 /g, a Total Pore Volume, (TPV) of 0.7-0.98, and a Pore Diameter Distribution whereby .ltoreq.20% of the TPV is present as primary micropores of diameter .ltoreq.100 .ANG., at least about 34% of TPV is present as secondary micropores of diameter of about 100 .ANG.-200 .ANG., and about 26%-46% of the TPV is present as mesopores of diameter >200 .ANG..
