Referring to Example 8.2.3, compute and plot the dimensionless exit concentration from the Berty reactor as a function of time for decreasing internal recycle ratio to the limit of PFR behavior.
Example 8.2.3
In Section 3.5 recycle reactors and particularly a Berty reactor were described. At high impeller rotation speed, a Berty reactor should behave as a CSTR. Below are plotted the dimensionless exit concentrations, that is, c(t)1Co, of cis-2-butene from a Berty reactor containing alumina catalyst pellets that is operated at 4 atm pressure and 2000 rpm impeller rotation speed at temperatures of 298 K and 427 K. At these temperatures, the cis-2-butene is not isomerized over the catalyst pellets.
