Abstract
Gas holdups, dispersion height, volumetric mass transfer coefficients and k (L)a of water and a yeast fermentation broth were studied in a co-current d ownflow contacting reactor. k(L)a and gas holdup increased with increasing superficial gas velocity and there was a parallelism between k(L)a and gas holdup. The values of k(L)a gas holdup, and dispersion height measured in t he air/fermentation broth system were all lower than those in air/water sys tem. (C) 1999 Published by Elsevier Science Ltd.
