Benzene (C6H6) is converted to cyclohexane (C6H12) by direct addition of hydrogen gas H2. The plant produces 100 Ib-moles/hr of cyclohexane. 90% of benzene fed to the process reacts to form cyclohexane. The composition of the stream entering the reactor is 80% moles H2 and 20% C6H6, and the product stream contains 4 moles C6H6.
a) The composition of the product stream.
b) The feed of C6H6 and H2.
c) The recycle rate of H2.
