Benzene → Cyclohexylbenzene

Reaction Conditions

Reaction Steps

2 g of a hydroalkylation catalyst comprising 0.15 wt % Pd on alumina/MCM49 20/80 wt/wt was sized and loaded into the reactor as described above. The catalyst was activated by ramping its temperature at 60° C./hour heating rate to 300° C. and holding it there for 2 hours in 2028 GHSV of flowing hydrogen at 3.44 bar (50 psig, 344 kPag) total pressure. Other details of the experimental procedure and the reactor were as described above. This reference case was established by running two experiments (A and B) parallel at identical conditions. As the results in Table 1 indicate, the catalyst yielded 35%-37% benzene conversion with 79% cyclohexylbenzene selectivity.
