Abstract

Abstract

A series of supercritical extraction experiments on rocks using CO₂ were carried out.The result was compared with chloroform extraction.70% of saturated hydrocarbons in rocks could be extracted out in 4 hours,and more than 90% of the extracts composed of saturated hydrocarbons,which could be directly injected into chromatography without the need of precedings.
