Abstract The extraction of oil from soybean with supercritical CO 2 was studied in a continuous-flow extraction apparatus at a pressure of 20-30MPa and a temperature of 308-323K.The results showed that the oil in soybean could be extracted out completely in this way. A mathematical model based on the hypothesis of fixed bed,plug-flow in integral run and mixed-flow in differential run is set up.Using this model we can calculate the results of integral extraction on the base of differential extraction which uses small materiel and occupies less time.The solving method of this model is simple.Under the condition in this paper,the deviation is less than 6%.
