Dehydrogenation of cyclohexane and hydrogenation of benzene in a fluidized bed of a palladium-alumina catalyst

Summary

• 1. An investigation was made of the transformations of cyclohexane at 468–470° and the hydrogenation of benzene at 260° at a pressure of 10 atm in a fkudized bed of a catalyst containing 2% of palladium supported by fluorinated alumina.

• 2. The catalyst was highly active and stable both in the dehydrogenation of cyclohexane and in the hydrogenation of benzene. In the range of space velocities investigated (1.5–3.2 h⁻¹) scarcely any change occurred in the extents to which these two hydrocarbons were transformed.

• 3. Under the hydrodynamic conditions adopted catalyst losses amounted so less than 0.5%
