METHOD FOR EXTRACTING AND UPGRADING OF HEAVY AND SEMI-HEAVY OILS AND BITUMENS

In investigating the extraction of oils (or precursor matter) from coal, oil shales, bitumens, heavy and semi-heavy oils with supercritical or near supercritical water, we discovered that conjoint use of such water and carbon monoxide can lead to significant upgrading of the precursor material durin...

Zusammenfassung:	In investigating the extraction of oils (or precursor matter) from coal, oil shales, bitumens, heavy and semi-heavy oils with supercritical or near supercritical water, we discovered that conjoint use of such water and carbon monoxide can lead to significant upgrading of the precursor material during extraction. Specifically, such upgrading manifested itself in the class compositions of the recover matter, i.e., in proportions of aliphatics and virtual elimination of as- phaltenes.
