Glucose is converted to ethanol by immobilized yeast cells entrapped in gel beads. The
specific rate of ethanol production is: qp = 0.2 g ethanol/g cell-h. The effectiveness factor for
an average bead is 0.8. Each bead contains 50 g/l of cells. The voids volume in the column is
40%. Assume growth is negligible (all glucose is converted into ethanol). The feed flow rate
is F = 400 l/h and glucose concentration in the feed is S0i = 150 g glucose/l. The diameter of
the column is 1 m and yield coefficient is 0.49 g ethanol/g glucose. The column height is 4
m.
