Abstract

The performance of an immobilized packed bed reactor for the hydrolysis of rice bran oil has been investigated and can be well described by a dispersion model with an average standard deviation of 0.0388. Global mass transfer coefficients estimated using the model and experimental data ranged from 0.095-0.482 min−1, depending on substrate flow rates. A dimensionless mass transfer correlation between the Sherwood number and the Reynolds number was obtained as NSh = 3.96 ×NRe2.07.

Abstract

La performance d'un réacteur à lit garni immobilisé pour l'hydrolyse d'huile de son de riz a été étudiée et peut bien se décrire par un modèle de dispersion avec un écart type moyen de 0,0388. Les coef. cients de transfert de matière globaux estimés à l'aide du modèle et des données expérimentales varient entre 0,095 et 0,482 min−1, selon les débits de substrat. Une corrélation de transfert de matière adimensionnelle entre le nombre de Sherwood et le nombre de Reynolds a été obtenue à savoir. NSh = 3.96 ×NRe2.07.
