1. A catalyst prepared by the steps which comprise:
- (a) adding to an asphaltene-containing hydrocarbonaceous oil charge stock a heteropoly acid and an oxide of a metal selected from Group IV through Group VIII and mixtures thereof and water;
(b) converting said heteropoly acid and metal within said charge stock by heating said oil to a temperature from about 120°
F. (43°
C.) to about 500°
F. (260°
C.) to produce at least one organometallic compound within said charge stock; and
(c) converting said organometallic compound within said charge stock under hydroconversion conditions including a temperature from about 650°
F. (343°
C.) to about 1000°
F. (538°
C.), a hydrogen partial pressure from about 500 psig (3448 kPa gauge) to about 5000 psig (34475 kPa gauge), and a space velocity from about 0.1 to about 10 volumes of oil feed per hour per volume of reactor to produce said catalyst.

Abstract
A catalyst prepared by the steps which comprise: (a) adding to an asphaltene-containing hydrocarbonaceous oil charge stock a metal compound, a heteropoly acid and water; (b) converting the metal compound and heteropoly acid within the charge stock by heating the oil to a temperature from about 120° F. (43° C.) to about 500° F. (260° C.) to produce at least one organometallic compound within the charge stock; and (c) converting the organometallic compound within the charge stock under hydroconversion conditions to produce the catalyst.
