The solubility of bio-diesel fuel components (methyl  esters of stearic and palmetic acid) in supercritical carbon dioxide is  studied. The results are described in the framework of Peng-Robinson  theoretical approach. The possibility of efficient separation of the target  compounds (methyl esters of fatty acids, glycerol) from re-esterification  reaction mixture and their purification using SC-CO2 are demonstrated.
