Abstract
Three different types of extraction processes, which used supercritical carbon dioxide ($SCCO_2$) and organic solvent, were attempted to improve the extraction yield of oil from Chlorella vulgaris: cosolvent-modified $SCCO_2$ extraction, $SCCO_2$ extraction with ultrasonic sample treatment in organic solvent, and static extraction with organic solvent followed by dynamic $SCCO_2$ extraction. Among these, the last $SCCO_2$ extraction process was found to be most effective in the extraction of oil. Compared with pure $SCCO_2$ extraction, the extraction yield of oil was observed to increase about 7 times.
