Recovery of hydrocarbons from hydrocarbon-containing materials

摘要

A method of extracting hydrocarbon-containing organic matter from a hydrocarbon-containing material includes the steps of providing a hydrocarbon-extracting solvent containing DMSO, Cellosolve, or a mixture thereof; contacting the hydrocarbon-containing material with the hydrocarbon-extracting solvent to form an extraction mixture; extracting the hydrocarbon material into the hydrocarbon-extracting solvent; and separating the extracted hydrocarbon material from a residual material not extracted.

主权项

1. A method of extracting hydrocarbon-containing organic matter from a hydrocarbon-containing material into a hydrocarbon-extracting solvent, comprising the steps of:
providing a first liquid comprising a hydrocarbon-extracting solvent comprising at least about 30% by volume DMSO and at least about 30% by volume 2-Ethoxyethanol; contacting the hydrocarbon-containing material with said hydrocarbon-extracting solvent such that an extraction mixture is formed, the extraction mixture comprising at least a portion of said hydrocarbon-containing organic matter extracted into the hydrocarbon-extracting solvent; and separating the extraction mixture from any residual material containing non-soluble material from the hydrocarbon-containing material that is not soluble in the hydrocarbon-extracting solvent.
