RESUMO
Abstract The kinetics of the extraction of tea seed oil with supercritical CO2was studied. A kinetic model of the extraction of tea seed oil using supercritical CO2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO2 inside the extraction bed as a function of extraction time and height of the extraction bed. The model could also simulate of the solute concentration in CO2 at the outlet of the extractor as a function of time. The effects of the parameters such as pressure and temperature on extraction yield and the process were investigated through the model. This model could simulate satisfactorily the process of extraction with an error between simulation data and experimental data of less than 10%.
