ABSTRACT PROCESS FOR PRODUCTION OF LIGHT HYDROCARBONS BY TREATMENT OF HEAVY HYDROCARBONS WITH WATER A process for converting heavy hydrocarbons into light hydrocarbons which comprises contacting, in a first zone, a heavy hydrocarbon having an API gravity at 25°C of less than about 20, such as Boscan heavy crude oil and tar sand bitumen, with a liquid comprising water, in the absence of externally added catalyst and hydrogen, while maintaining the first zone at a tempera- ture between about 380° and about 480°C and at a pres- sure between about 5000 kPa (about 725 psig, about 49 atm) and about 15,000 kPa (about 2175 psig, about 148 atm), for a time sufficient to produce a uniform reac- tion mixture; forwarding the uniform reaction mixture to a second zone wherein the temperature and pressure con- ditions of the first zone are maintained for a time suf- ficient to separate the uniform mixture into a residue and a phase comprising light hydrocarbons, gas 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.
