Question

Cyclohexane (C6H12) can be made by the reaction of benzene (C6H6) with hydrogen according to the
following reaction:

C6H6 + H2 → C6H12

For the process shown in the figure, determine the a) composition of the product and b) the ratio of
the recycle stream to the fresh feed. The overall conversion of benzene is 95% and the single pass
conversion is 20%. Assume that 20% excess hydrogen is used in the fresh feed, and that the
composition of the recycle stream is 22.74 mol% benzene and 78.26 mole % hydrogen.

4. Cyclohexane (C6H12) can be made by the reaction of benzene (CsHs) with hydrogen according to the
following reaction: C,H, + H2 →C,H12
For the process shown in the figure, determine the a) composition of the product and b) the ratio of
the recycle stream to the fresh feed. The overall conversion of benzene is 95% and the single pass
conversion is 20%. Assume that 20% excess hydrogen is used in the fresh feed, and that the
composition of the recycle stream is 22.74 mol% benzene and 78.26 mole % hydrogen.
