Benzene CsHo is converted to cyclohexane C&H12 by direct reaction with t2. The fresh feed to the process is 260 L/min of CaHs plus 950 L/min of H2 at 100 °C and 150 kPa. The single pass conversion of H2 in the reactor is 48% while the overall conversion of H2 in the process is 75%. The recycle stream contains 90% H2 and the remainder benzene (no cyclohexane). 1) Write a balanced equation for the above reaction. 2) Determine the partial pressure of H2 and CoHs in the fresh feed.
