An alternative process for converting benzene to cyclohexane also uses a supported noble metal catalyst, but carries out the reaction in the liquid phase, at a temperature of 160 °C and pressure of 100 bara, in a slurry reactor. The catalyst has piece density 1100 kg/m³. Laboratory scale experiments in an isothermal continuous well-mixed reactor, cooled in a bath of coolant, have determined that with a high rate of hydrogen agitation and 10wt% loading of catalyst, a conversion of 95% can be attained with 40 minutes residence time.
