A process for converting heavy hydrocarbons into light hydrocarbons which comprises contacting, in a reaction zone, a heavy hydrocarbon having an API gravity at 25°C. of less than about 20, such as Boscan heavy crude oil or tar sand bitumen, with a liquid comprising water and with an effective amount of selected catalyst materials such as iron (II and/or III) oxides, sulfides or sulfates, in the absence of externally added hydrogen, at a temperature between greater than about 340°and about 480°C. and at a pressure between about 1350 kPa (about 196 psig, about 13.2 atm) and about 15,000 kPa (about 2175 psig, about 148 atm), for a time sufficient to produce a residue and a vapor phase comprising light hydrocarbons, gaseous product and water, withdrawing the residue and said phase from the second zone; and recovering a light hydrocarbon product having an API gravity at 25°C. of greater than about 20 and substantially free of vanadium and nickel values, i.e., less than 50 ppm, preferably less than 30 ppm, a gaseous product, and a residue is disclosed.
