摘要：

Soxhlet versus ultrasonic extraction efficiency on the immature Puertollano oil shale has been tested. The yields from the two methods are compared. The extracts were compared by gas chromatography and geochemical parameters such as CPI and pristine/phytane ratio calculated. The ultrasonic extraction procedure is an effective, quick and easy method which does not change the biomarker ratios of the bitumen. Minor efficiency differences can be observed among the solvents allowing a choice on the basis of handling properties. Carbon disulfide and chloroform are easiest to eliminate from the extract.
