Claim 15:
16. A system for processing a hydrocarbon feedstock, the system comprising:
a supercritical carbon dioxide extraction unit configured to contact a hydrocarbon feedstock with supercritical carbon dioxide to form at least an extract emulsion and a pitch emulsion;
a supercritical water gasification unit in fluid communication with the supercritical carbon dioxide extraction unit, the supercritical water gasification unit configured to contact the pitch emulsion with supercritical water to form a gasified product; and
a degassing unit in fluid communication with the supercritical water gasification unit, the degassing unit configured to separate the gasified product into at least a product gas and a product emulsion, wherein the degassing unit is in fluid communication with the supercritical carbon dioxide extraction unit such that at least a portion of the product emulsion is recycled to the supercritical carbon dioxide extraction unit.
