A process for converting a heavy hydrocarbon charge containing asphaltenes and metal, sulfur and nitrogen impurities, in order to obtain products of lower boiling point and lower impurities content, wherein a mixture of said charge with hydrogen is contacted with a catalyst composition comprising at least two essential elements: (a) soot of the cenosphere type, resulting from the combustion of liquid heavy hydrocarbon charges containing at least one metal of the iron, nickel and vanadium group, said metal being also present in said soot, and (b) at least one catalytic metal compound distinct from the element (a) and selected from the compounds of metals of groups VB, VIB, VIIB and VIII.
