Summary

  1. 1.

    An investigation was made of the change in the activity of a 0.005% Pt-Al2O3 catalyst after it had been treated with water vapor mixed with hydrogen at 420° with a water vapor pressure of 60–80 atm and also after the catalyst was treated with hydrogen, freed from oxygen and water, at 500°. It was established that water promotes the alumina-platinum catalyst not only in benzene hydrogenation, but also in cyclohexane dehydrogenation. The promoting effect of water is reversible.

  2. 2.

    Dehydration of the alumina-platinum catalyst by treatment at 550° with hydrogen freed from oxygen and water produced practically complete deactivation of the catalyst in benzene hydrogenation and cyclohexane dehydrogenation.
