Upgrading heavy hydrocarbons using supercritical or near super-critical carbon dioxide

A process for upgrading a heavy hydrocarbon mixture involves: i) contacting the heavy hydrocarbon mixture with supercritical or near-supercritical CO2under conditions suitable to produce a pumpable lighter fraction and a heavier residue from said hydrocarbon mixture; and ii) utilising at least a par...

description	A process for upgrading a heavy hydrocarbon mixture involves: i) contacting the heavy hydrocarbon mixture with supercritical or near-supercritical CO2under conditions suitable to produce a pumpable lighter fraction and a heavier residue from said hydrocarbon mixture; and ii) utilising at least a part of the heavier residue obtained in step (i) to generate steam for use in further extraction of the heavy hydrocarbon mixture and/or to produce electricity, wherein the CO2used in step (i) and/or generated in step (ii) is either captured and recycled or is stored subsurface (e.g. permanently stored subsurface).
