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.
