Cyclohexane (C,H12) can be made by the reaction of benzene with hydrogen according to the
following reaction:
C,H6 + 3H2
C,H12
For the process shown in below, determine the ratio of the recycle stream to the fresh feed stream if
the overall conversion of benzene is 95% and the single-pass conversion is 20%, and the ratio of
unreacted benzene in the product stream to the unreacted benzene in the recycle stream. Assume
that 20% excess hydrogen is used in the fresh fed, and that the composition of the recycle stream is
22.74 mol% benzene and 78.26 mol% hydrogen.
