Key words: : extraction, supercritical CO₂, oil, heavy oil residues

The method for purification of oils and their heavy residues from asphaltenes and metals based on different solubilities of the main constituents of oil and its undesirable components in supercritical fluids (CO₂). Effects of temperature, pressure and oil dilution with carbon dioxide, as well as tar dilution with light hydrocarbons and CO₂ onto asphaltenes and metals removal are studied. The method provides with advanced purity of raw oil used further to produce final products (gasoline, base oils).
