Efficient oil shale recovery method

摘要

A method for recovering hydrocarbons from oil shale and other carbonaceous materials has the steps of preparing a biomedium of microorganisms, water, and nutrients; providing shale laden with oil; treating oil shale with the biomedium; mechanically agitating the treated oil shale and biomedium approximately twelve hours to form a liquid suspension; and separating the components of the liquid suspension to yield a hydrocarbon mixture.
