Abstract
A system for making low volatile carbonaceous material including a digestion vessel in communication with a carbonaceous material feedstock unit for producing a digested carbonaceous material; an extraction vessel in communication with the digestion vessel, the extraction vessel containing supercritical carbon dioxide fluid for extracting hydrocarbons from the digested carbonaceous material to produce an extract solvent and the low volatile carbonaceous material; and at least one separation vessel in communication with the extraction vessel for separating the extract solvent to a carbon dioxide gas and a stream of extracted hydrocarbons.
