摘要

Abstract

The solubility of red palm oil (RPO) in supercritical carbon dioxide (scCO

) was determined using a dynamic method at 8.5-25 MPa and

313.15-333.15 K and at a fixed scCO

flow rate of 2.9 g·min-1 using a full factorial design. The solubility was determined under low pressures and temperatures as a preliminary study for RPO particle formation using scCO

. The solubility of RPO was 0.5-11.3 mg·(g CO

)

-1

and was significantly affected by the pressure and temperature. RPO solubility increased with pressure and decreased with temperature. The Adachi-Lu model showed the best-fit for RPO solubility data with an average relative deviation of 14% with a high coefficient of determination

of 0.9667

whereas the Peng-Robinson equation of state thermodynamic model recorded deviations of 17%-30%.
