摘要: This invention relates to the extraction of oil shales and tar sands by using a solvent under supercritical conditions at temperature within 200° C. or its critical in order effect kerogen from sand shale. In case considerable heat needs be applied shale before effective can occur this may carried out range 370° 450°
