A process of preparing a highly dispersed (colloidal or submicron size) heterogeneous catalyst for the hydrothermal conversion of heavy oils and residua is described. The process comprises preparing a reverse micellar dispersion by mixing water, an organic solvent, and an ionic or neutral surfactant to which is added an aqueous solution of a metal salt. The metal salt is reduced to a colloidal dispersion of the catalyst in a mixed water-organic liquid phase. The colloidal catalyst is then blended into resid or heavy oil fractions, and the blend is treated under hydrothermal conditions.

A process for catalytically converting a heavy hydrocarbon feedstock to lower boiling liquids, comprising: preparing a colloidal dispersion of a metal catalyst in a mixed water-organic liquid phase by admixing an effective amount of an aqueous salt solution of a metal with an inverse micellar disper

A process for catalytically converting a heavy hydrocarbon feedstock to lower boiling liquids, comprising: preparing a colloidal dispersion of a metal catalyst in a mixed water-organic liquid phase by admixing an effective amount of an aqueous salt solution of a metal with an inverse micellar dispersion of said mixed water-organic liquid phase and reducing or precipitating said metal salt to an elemental metal or metal compound; and contacting said feedstock with said colloidal dispersion in the presence of hydrogen and at a temperature necessary to effect said catalytic conversion.
