Key words: supercritical fluids, group composition, asphaltenes, supercritical fluid extraction, carbon dioxide, anti-solvent, fractionation
The review article examines information on modern methods of separating oils and oil residues in the analysis of group composition using supercritical fluids. The features of the influence of the composition and properties of individual group components of oil samples on further processing has been shown. Traditional methods of separating petroleum feedstock into group components has been briefly reviewed. The results of modern studies of extraction methods for separating oil samples using supercritical fluids has been shown. Information is presented on new methods for the extraction of asphaltenes and fractionation of heavy oils and oil residues using СО2.
