摘要: Abstract Posidonia oceanica residues were extracted with supercritical CO 2 in order to isolate phenolic compounds. The process was optimized by developing a mathematical model based on mass transfer mechanism consisting of adsorption fluid the solid particles, desorption solute and convective phase along column. Henry relation between concentrations surface ( Cs ) q approximated describe adsorption/desorption equilibrium. parameters such as solid-liquid film coefficient kf ), molecular diffusivity D AB axial dispersion ax estimated using empirical methods. linear driving force applied improve yield total acid recovery. optimum elicited 25 MPa, 323.15 K co-solvent ratio 20% yielding 34.97 μg per gram dry feed satisfactorily described extraction which can be used for scale-up purposes.
