In a fermentation process sugar (A) is converted to ethanol (C) in the presence of yeast (B) in a batch reactor. In
a simple model the process can be presented as:
A+B4C+4CO2,-rA=kCACB
The starting solution contains 10 weight percent of sucrose (C12H22O11) in water.
a. Find the reaction time needed to achieve 99% conversion of the sucrose for an initial yeast
concentration of 10M. Initial experiment found that if the concentration of yeast is
maintained at 1M, the reaction takes 2 hours to achieve 99% conversion of sucrose.
Assume the density of the solution equals the density of water.
b. Determine to total cycle time of the process. Use time values from Table 5.3 for tf,te, and
tc.
