| Zusammenfassung: | A process of upgrading coal with carbon dioxide, comprising the steps of:
providing a carbon dioxide-containing fluid having a carbon dioxide concentration greater than that of air;
allowing the carbon dioxide-containing fluid to contact coal in a coal upgrading apparatus for a period of time, wherein the coal is not in a water slurry;
allowing the carbon dioxide-containing fluid to be vented from the coal upgrading apparatus thereby removing at least some non-polar constituents from the coal. |
