Kinetic study on extraction of red pepper seed oil with supercritical CO2
Chinese Journal of Chemical Engineering(2014)
摘要
A mathematical model for extraction of red pepper seed oil with supercritical CO2 was proposed. Some factors influencing the process were investigated, including operation pressure, temperature and extraction yield Xe (%). The model was solved by the method of weighted residuals and used to simulate the process numerically. The kinetic equation is expressed as Xe = −16.8606exp(−t/9.98177) + 16.95457 and the simulation results are in excellent agreement with the experimental data. The optimal operating parameters are 30 MPa, 318 K and 60 min.
