Abstract

The present invention provides a process for the upgradation of petroleum residue into useful fractions by subjecting petroleum residue in the presence of a solvent and ferrous sulphate catalyst to a pressure in the range of 10 atm. to 120 atm., temperature in the range of 380-420° C., for a period in the range of 0-120 minutes, in a reactor vessel, in an inert atmosphere. The charge is then cooled to room temperature and the product gas released through scrubbers. The residue is re-heated, if required, for free flow of liquid product. The resulting liquid product is distilled to obtain useful fractions.
